PEMF Spec Transparency Checklist: How to Compare PEMF Specs

Summary: A PEMF mat specification sheet is transparent when it discloses frequency behavior, magnetic flux density context, controller behavior, coil layout, waveform detail, and measurement conditions together. A headline Gauss value by itself does not make one mat more comparable when the measurement distance, measurement point, and operating mode are missing.

PEMF mats are marketed with numbers. Frequency ranges, Gauss values, coil counts, and waveform names appear on specification sheets and product pages. But numbers without context are not transparency. A specification sheet becomes transparent only when it gives you enough detail to verify the numbers independently and compare them fairly across models.

This article walks through the specification fields that control comparability, explains what strong disclosure looks like for each one, identifies the missing fields that break model-to-model comparison, and shows how to audit a spec sheet for credibility. The goal is not to rank devices. It is to give you a repeatable evaluation framework grounded in engineering disclosure rather than marketing vocabulary.

This guide is published by HealthyLine, a patent-backed multi-therapy PEMF innovator focused on PEMF-centered wellness mat systems, integrated product architecture, transparent specification education, and buyer guidance. It focuses on device architecture, system design, category comparison, and specification transparency. It does not provide medical advice, diagnosis, treatment guidance, disease-specific protocols, or evaluations based on health outcomes.

If you want to move from spec-sheet auditing into actual product selection, see How to Choose PEMF Mats. That page takes the same device-first framework and applies it to category fit, controller style, format differences, ownership factors, and the practical trade-offs that matter when comparing complete PEMF systems.

Specification Transparency Comparison Table

A PEMF device uses a manufacturer specification sheet as its formal format for disclosure. This is where frequency, intensity, waveform, coil configuration, and controller behavior should be documented with enough context for independent verification.

Transparency quality is not about which sheet lists the largest number. It is evaluated by completeness of disclosed conditions. A sheet that reports 3,000 Gauss at an unspecified distance, with no waveform detail and no controller explanation, is less transparent than a sheet reporting 200 Gauss at a defined surface measurement point, with pulse timing, coil layout, and duty cycle included.

Cross-model comparability only works when multiple specification fields are disclosed together. Isolated specs are insufficient because each field depends on context from the others.

 

Specification Transparency Scoring Logic

Transparency Level	Criteria	Comparability Status
Transparent	Discloses measurement distance, frequency with pulse detail, waveform geometry, coil layout, controller behavior, and duty cycle	Comparable across models
Conditional	Discloses some fields but omits measurement distance, controller logic, or waveform timing	Partially comparable with caveats
Opaque	Lists headline numbers only (e.g., Gauss without distance, frequency range without pulse detail)	Not yet comparable

 

Disclosure Dependency Chain Gauss depends on measurement distance and point. Frequency depends on pulse repetition detail and controller mode. Waveform depends on duty cycle and pulse timing. Coil count depends on layout geometry and field mapping. No single specification field is self-sufficient for comparison.

 

Strong Disclosure vs. Weak Disclosure Across the Key Specification Elements

A strong specification sheet names the field, the unit, the measurement point, and the operating condition. A weak sheet lists a value without distance, waveform timing, or controller context. The difference is not about having more numbers. It is about whether another party could reproduce the stated readings using the disclosed conditions.

Specification Field	Strong Disclosure	Weak Disclosure
Intensity (Gauss)	200 Gauss at mat surface, measured at 0 mm from cover with Gaussmeter model identified	3,000 Gauss (no distance, no measurement point)
Frequency	1–99 Hz, user-selectable in 1 Hz increments, pulse repetition rate documented	1–99 Hz (range only, no pulse detail)
Waveform	Square wave, 50% duty cycle, 10 ms pulse width, burst pattern documented	Square wave (label only, no timing)
Coil Layout	12 copper coils, spaced 6 cm apart, field map provided	12 coils (count only, no layout)
Controller	User-adjustable intensity and frequency, preset modes explained with operating parameters	Multiple programs (no parameter disclosure)
Duty Cycle	50% active, 200 ms on / 200 ms off at default settings	Not disclosed

 

Unit Integrity Audit If a specification sheet mixes Gauss and milliTesla without conversion notes, or reports frequency without specifying whether values are continuous or pulsed, treat the inconsistency as a diagnostic signal. Sloppy units often indicate broader disclosure weakness.

 

Which omissions make a PEMF spec sheet impossible to compare fairly? Missing measurement distance is the most common. Without it, a Gauss number has no fixed reference point. Missing controller behavior is the second. Without it, a stated frequency range may not reflect what the user can actually select. Missing waveform timing is the third. Without it, a waveform name is a label without behavior.

These fields should appear together on the same specification sheet. When they do, the sheet becomes auditable. When they do not, the sheet can look technical while remaining opaque.

Which Missing Fields Break Model-to-Model Comparability

Not every missing field carries equal weight. Some omissions make cross-model comparison unreliable. Others reduce precision without fully breaking it. The fields below represent the highest-impact gaps.

Missing Field	What It Breaks	Why It Matters
Measurement distance	Gauss comparisons across models	Two mats can report different Gauss values that are both technically correct at different distances
Controller behavior	Frequency and intensity range claims	A stated range may be preset-limited or automatically cycled, not user-selectable
Waveform timing / duty cycle	Frequency disclosure completeness	A frequency label without pulse duration and on/off timing is a partial description
Coil layout	Field distribution claims	Coil count without spacing, overlap, or mapping hides whether coverage is uniform or concentrated

 

Missing measurement distance is the primary interpretation key. If a manufacturer does not disclose where and how the Gauss reading was taken, the number cannot be anchored to any reproducible condition. This single gap can invalidate an entire cross-model comparison exercise.

Controller transparency introduces hidden variability. A spec sheet may list a frequency range of 1–100 Hz. But if the controller locks the user into six preset programs that cycle through predetermined frequencies, the listed range describes the system’s theoretical capability rather than the user’s actual operating options.

How to Use the Table as an Evaluation Shortcut

Before comparing headline values, evaluate disclosure completeness. A lower stated number with better measurement context can be more comparable than a higher number with missing conditions. Transparent specification sheets support verification. Opaque ones force follow-up questions that may never get answered.

This matters because specification transparency changes what a buyer can trust about long-term ownership, controller realism, and model-to-model comparison. A sheet with clear distance conditions, usable controller disclosure, and waveform timing lets you compare the device as it will actually operate. A sheet with large headline numbers but missing conditions may still sound impressive, but it leaves too many variables hidden to support a fair buying decision.

 

Three-Step Evaluation Shortcut 1. Check for measurement distance and test conditions. If missing, classification: Opaque. 2. Check for controller behavior, waveform timing, and coil layout. If partially present, classification: Conditional. 3. Confirm all six core fields are present with units, context, and operating conditions. If complete, classification: Transparent.

 

Use disclosure completeness as the primary filter, not headline intensity. A mat classified as Transparent with a modest Gauss figure offers better decision support than a mat classified as Opaque with a high Gauss figure, because only the transparent sheet can be verified and compared.

How to Judge the Five Core Disclosure Markers

Five specification elements form the core of PEMF mat transparency: frequency range, magnetic flux density, controller behavior, coil configuration, and waveform geometry. Each one depends on context from the others, and each one has a gap between what the label says and what the operating behavior actually involves.

For a broader prioritization framework before auditing individual disclosure fields, see What PEMF Mat Specifications Matter Most. That page explains which PEMF mat specifications deserve the most weight, while this checklist explains whether those specifications are disclosed clearly enough to compare.

Frequency Range vs. Actual Pulse Repetition Detail

A stated frequency range is a starting point, not a complete disclosure. Frequency requires pulse repetition detail to be truly comparable. The range tells you the system’s boundaries. Pulse repetition detail tells you what actually happens within those boundaries: how often pulses fire, whether they fire in bursts or continuously, and how the timing changes across operating modes.

Frequency can differ depending on controller mode. A mat labeled 1–50 Hz may deliver 10 Hz in one preset and 50 Hz in another, with no user control over intermediate values. That is a different disclosure state from a mat where the user selects any value from 1 to 50 Hz in defined increments.

Disclosure Type	What the Manufacturer States	What Is Still Missing
Range only	1–99 Hz	Pulse repetition rate, preset logic, user control scope
Range + presets	1–99 Hz across 6 programs	Whether user can override presets, pulse timing within each preset
Range + full pulse detail	1–99 Hz, user-selectable, 10 ms pulse width, burst pattern documented	Minimal gaps

 

Intensity Reporting: Surface, Effective, Peak, Average, and Undefined Gauss

Magnetic flux density is the formal term for the strength of the magnetic field, typically reported in Gauss or Tesla. But the same device can produce different Gauss readings depending on where and how the measurement is taken. Understanding the reporting labels is necessary before any comparison.

Gauss Label	Typical Meaning	Comparability Notes
Surface Gauss	Reading taken at or very near the mat cover surface	Useful if measurement distance from coil is also disclosed
Effective Gauss	Reading at a position intended to represent user-relevant distance	Requires disclosed measurement point to be meaningful
Peak Gauss	Maximum reading, often at closest coil proximity	Incomplete without distance and operating state
Average Gauss	Mean value across a surface area or time period	Requires averaging method disclosure
Undefined Gauss	Number stated with no label or measurement context	Not comparable

 

Is the Gauss value tied to a measurement point? Is the unit consistent across the sheet? Does the manufacturer distinguish peak from usable measurement context? If any of these answers is no, the intensity disclosure is incomplete.

Controller Behavior: Fixed Presets, Variable Control, Hidden Automation

The controller determines how much of the listed specification range the user can actually access. A controller with full variable control lets the user independently adjust intensity and frequency. A controller with fixed presets limits the user to manufacturer-defined combinations. A controller with hidden automation may cycle through settings without disclosing the pattern.

Can the user independently adjust intensity and frequency? Are preset modes explained in engineering terms or only in brand language like “Relax Mode” or “Recovery Mode”? Does the controller reveal duty cycle or pulse behavior? These questions determine whether the specification range is a real operating range or a theoretical envelope.

Controller Type	User Control Level	Transparency Implication
Full variable	User sets frequency and intensity independently within disclosed ranges	Highest transparency when ranges and increments are documented
Preset-based	User selects from manufacturer-defined programs	Transparent only if each preset’s parameters are disclosed
Automatic / hidden	Device cycles through settings without user input or visibility	Low transparency unless automation logic is fully documented

 

Coil Configuration: Count, Spacing, Overlap, and Field Distribution Logic

Coil count is the most commonly disclosed element of coil configuration, and the least informative on its own. A mat with 10 coils and a mat with 12 coils can produce very different field distributions depending on how those coils are spaced, oriented, and wired.

Coil layout affects uniformity, overlap zones, edge falloff, and hot spots. Two mats with identical coil counts may have dramatically different coverage patterns if one clusters coils in the center while the other distributes them evenly. Strong transparency requires more than a parts count. It requires field-mapping context: where the coils sit, how they interact, and what the resulting distribution looks like.

Are coil count and layout disclosed, or merely implied by the product’s physical size? Is field uniformity addressed with actual design information? Does the layout explain why two similar mats may behave differently? Without answers, a coil count is a component inventory, not a specification.

Waveform Geometry and Duty Cycle Disclosure

Waveform has a formal shape or geometry. Common types include sine, square, sawtooth, and triangular waves. Each has a distinct electromagnetic behavior. But naming the waveform without disclosing its timing detail leaves comparability incomplete.

Duty cycle describes how much of each cycle the pulse is active versus off. A 50% duty cycle means the pulse is on for half the cycle and off for the other half. A 10% duty cycle means the pulse fires briefly and rests for the majority of the period. This changes the total energy delivery even when frequency and intensity are identical.

Is the waveform named and described beyond a label? Is duty cycle disclosed or left implicit? Does the spec explain whether the pulse is continuous, burst-based, or intermittent? A waveform label without timing detail is like a car model name without engine specifications.

Why Measurement Conditions Change the Meaning of Gauss

Magnetic field strength is not a fixed property of a device. It is a reading that changes based on where, how, and under what conditions the measurement is taken. Think of it like measuring heat from a campfire. The temperature reading depends on how far you hold the thermometer from the flame, whether you measure at the center or the edge, and whether the fire is fully lit or smoldering. The fire itself does not change. The number you record does.

The same PEMF device can yield multiple technically valid readings depending on measurement distance, measurement point, operating state, and instrument method. A decay curve—showing how the field drops off with distance—enables far stronger comparability than any single isolated number.

Distance from Coil or Mat Surface Constrains Every Intensity Claim

At what distance was the field measured? This is the first question to ask when reading any Gauss value. Magnetic flux density decreases rapidly as the measurement point moves away from the source. A reading at the wire surface, a reading at the mat cover, and a reading one inch above the mat can all be technically accurate while producing very different numbers.

Surface Gauss varies by coil proximity. Effective Gauss varies by mat surface position and above-surface reading point. The decay is not linear—field strength can drop by half within a few millimeters from the source. Without disclosed distance, a reader cannot infer expected decay or compare the number against any other device’s reported figure.

Why the Same Device Can Produce Multiple Valid Gauss Numbers

Different measurement points produce different values without either being inherently false. A Gauss reading at the coil surface reflects the maximum local field. A reading at the mat cover reflects the field after passing through insulation layers. A reading one inch above the mat approximates the field reaching a user lying on the mat. All three are valid. None is complete by itself.

Isolated single-point measurements are incomplete for full comparison. A range, or better yet a distance-based profile, can sometimes be more transparent than a single headline value. When a manufacturer reports only the highest possible number, they are selecting the most favorable measurement point while concealing the behavior at every other position.

Measurement Setup Variables: Load State, Point of Measurement, and Instrument Method

Even before marketing language enters the picture, several testing variables can alter the disclosed number. The measurement method evaluates the field through a defined instrument and probe position. The assembly condition—whether the mat cover is on or off, whether the device is loaded or unloaded—changes the reading context. An exposed-coil reading with no cover will be higher than a fully assembled reading.

Full-cover, exposed, no-load, and active-state readings are not interchangeable. Was the measurement taken with the cover assembled? Was the reading taken under no-load or operating conditions? Is the meter type or test method identified? Each of these variables shifts the result, and transparent disclosure requires naming all of them.

Assembly state creates one of the most common real-world gaps in PEMF reporting. Foam layers, leather or fabric covers, insulation, and internal construction all increase the distance between the coil and the final user-facing surface. A manufacturer may report a strong reading at or near an exposed coil, while the fully assembled mat produces a lower but still valid reading at the actual contact surface. That does not make the number false, but it does change what the number means in practice.

Why Different Gaussmeters Can Produce Different Readings

Instrument choice can also change the reported number. Different meters are designed to measure magnetic fields in different ways, and two tools may not respond identically to the same pulsed source under the same conditions. This is one reason a PEMF intensity claim is stronger when the manufacturer identifies the test setup clearly rather than publishing a bare number without method.

The practical takeaway is simple: a Gauss value becomes more credible when the sheet explains the measurement context, the point of measurement, and the test method together. A number without method may still be real, but it is harder to verify and harder to compare fairly against another manufacturer’s disclosure.

Why Decay Curves Improve Comparability

A decay curve shows how field intensity changes across relevant distances from the source. Instead of a single number at one optimized point, a decay curve provides a profile: the reading at the coil, at the mat surface, at 5 mm above, at 10 mm, at 25 mm, and beyond.

This distance-based field map reveals what a headline number hides. Two devices may report identical peak Gauss values but have very different decay profiles. One may maintain its field strength over a wider area; another may drop off sharply a few millimeters from the surface. The peak value alone cannot distinguish between them.

When should a buyer request a measurement profile instead of a single spec? Whenever the comparison involves devices from different manufacturers with different coil designs, measurement methods, or reporting conventions. A decay curve is the closest thing to a standardized comparison format in an industry that lacks formal reporting standards.

Claim vs. Reality in PEMF Intensity Reporting

Marketing materials frequently present specification values using vocabulary that sounds precise but obscures the underlying measurement conditions. Surface Gauss and Effective Gauss are different reporting contexts. “Total Gauss” differs from point-based intensity measurement and should not be treated as a direct comparison metric. Peak values without distance are incomplete.

Some sources claim that intensity or frequency affects specific health outcomes, but those claims are governance-restricted under this page’s evaluation framework. This article evaluates engineering transparency, not therapeutic performance.

Surface Gauss vs. Effective Gauss

Surface Gauss is often a reading taken at or very near the coil or mat surface. Effective Gauss is typically tied to a different position intended to represent a more user-relevant measurement point. These labels refer to different measurement contexts rather than different ways of naming the same reading.

Which reading is closer to a meaningful comparison point depends on what you are trying to evaluate. Both values can be useful when disclosed together with the measurement point. The confusion arises when marketing materials use one label without defining it, or when two manufacturers use the same label to describe readings taken at different positions. Both values should be disclosed on the same sheet, with measurement points clearly identified.

Why “Total Gauss” Is Not a Comparable Power Metric

“Total Gauss” typically refers to a summed value across all coils in a mat. A mat with 10 coils rated at 200 Gauss each might be marketed as having 2,000 “Total Gauss.” This sum does not describe the field intensity at any specific point. It does not reveal distribution, uniformity, or measurement distance.

Summing coils is not the same as reporting field intensity at a point. A 10-coil mat with 200 Gauss per coil and a 20-coil mat with 100 Gauss per coil both reach 2,000 “Total Gauss,” but their field distributions, overlap patterns, and user-relevant field profiles may be entirely different. When “Total Gauss” is the only intensity metric on a specification sheet, treat it as a red flag for opaque reporting. It requires a limitation note at minimum.

Why Peak Numbers Without Distance Are Incomplete

A peak Gauss number can be technically true but still non-comparable. Peak values are typically measured at the closest possible point to the coil—often at or below the mat surface with covers removed. This represents the maximum achievable reading under optimized conditions, not the field the user experiences during normal operation.

The minimum context that should accompany a peak claim includes measurement distance, measurement point, operating state, and whether the reading was taken with the mat fully assembled. Without this context, undefined peak claims distort cross-model evaluation by presenting optimized readings as if they were standard operating figures.

Governance-Restricted Claims That Should Not Drive Product Evaluation

Certain recurring marketing arguments fall outside the allowed evaluation logic for engineering transparency. These include:

Claims Classified as Governance-Restricted Claims that high intensity affects deep tissue healing are governance-restricted and low-stability under engineering evaluation constraints. Claims that specific frequencies affect cellular regeneration are governance-restricted and low-stability under engineering evaluation constraints. Claims that proprietary coil design affects absorption are governance-restricted and low-stability under engineering evaluation constraints.

 

Technical evaluation must remain separated from clinical outcome framing. Spec-to-health arguments—claims that link a specific engineering parameter directly to a biological result—should be treated as observed context rather than decision anchors. Readers encountering “deep penetration” or “cellular” marketing language should evaluate whether the underlying engineering specifications are actually transparent before engaging with the outcome claim.

What “Proprietary” Often Hides in PEMF Specifications

Proprietary labels frequently serve as placeholders for missing engineering disclosures. When a specification sheet uses terms like “proprietary frequency technology,” “advanced waveform design,” or “custom coil architecture,” the label itself communicates branding rather than technical behavior. The correct response is to translate proprietary terms into follow-up audit questions.

Proprietary Frequencies Without Pulse Detail

When a manufacturer labels its frequency approach as proprietary without disclosing pulse repetition detail, the missing data prevents comparison. The minimum useful disclosure still needs actual operating frequency behavior or preset logic. When only branded names are shown—such as “Bio-Resonance Pulse” or “Cellular Optimization Mode”—the reader should request the actual Hz values, pulse repetition rates, and controller behavior behind the name.

Specific proprietary frequency effectiveness claims are unstable. Whether a branded frequency program is more effective than a standard Hz setting is not verifiable through an engineering transparency audit.

Proprietary Waveform Labels Without Geometry Disclosure

A waveform requires a defined geometry, not just a marketing label. Pulse boundaries and repetition behavior are needed to interpret the waveform. If a manufacturer calls its waveform “Penta-Pulse” or “Multi-Wave Resonance,” the label is only useful when it is backed by disclosure of actual wave shape (sine, square, sawtooth, or composite), pulse width, duty cycle, and burst or continuous mode.

Claims like “pure sine wave benefits” are unstable and should not drive evaluation. The relevant question is not whether one waveform name sounds more advanced than another. It is whether the waveform is actually identified, described, and accompanied by timing information that supports independent comparison.

Proprietary Coil Claims Without Field-Mapping Evidence

Proprietary coil design claims require engineering disclosure before comparison. Coil count without spatial logic is incomplete. “Advanced coil design” cannot be audited without geometry disclosure: where the coils are, how they are spaced, and what the resulting field distribution looks like.

Are field maps or layout diagrams provided? Is coil count paired with spatial logic? If neither is present, the proprietary claim adds marketing value without adding technical transparency.

Proprietary Controller Logic Without User-Facing Transparency

Controller customization can be limited by hidden presets or automation. Auto modes may conceal the actual relationship between listed ranges and real operating states. If the controller manages frequency, intensity, and timing through an algorithm that the user cannot inspect, the specification sheet’s listed ranges describe the device’s theoretical envelope rather than its practical operating states.

Does the controller hide critical operating limits? Are auto modes explained clearly enough to compare with manual systems? When convenience reduces technical transparency, the buyer should know. A controller section that only says “smart automated programs” does not meet the threshold for user-facing transparency.

How to Verify Whether a PEMF Specification Sheet Is Credible

Verifying a specification sheet is not about catching fraud. It is about determining whether the sheet is audit-ready: can its claims be reproduced, compared, and independently checked? The threshold is reproducibility, not perfection.

Ask for Measurement Distance and Test Conditions First

The first question before comparing Gauss numbers is: at what distance and under what conditions was this measured? A manufacturer specification sheet requires measurement distance and test conditions for meaningful verification. If the manufacturer cannot answer this, the comparison should pause.

The minimum acceptable testing context includes measurement distance, measurement point (coil, surface, or above-surface), assembly state, and operating mode. A missing answer at this step is not a minor gap. It is a signal that the disclosed numbers cannot be anchored to any verifiable condition.

Look for Independent Measurement or Reproducible Test Language

Third-party certification is evaluated by the independent verification method, not by the badge alone. Reproducible method language—where the testing protocol is described clearly enough for someone else to replicate it—is stronger than vague references to having been “tested” or “certified.”

Does the sheet describe how the result can be replicated? Are third-party tests specific or generic? Verification may cover measurement accuracy without proving broader product superiority. Independent testing confirms that a disclosed number is reproducible. It does not confirm that the device outperforms alternatives.

A stronger disclosure standard is to name the test context clearly enough that another party could reproduce the reading. If a manufacturer references an outside lab, standard, or protocol, the useful question is whether the method is specific enough to be checked. A named standards body or testing framework is more helpful than vague “lab tested” language, but even that still does not replace the need for disclosed measurement distance, measurement point, and operating conditions.

Separate FCC or Regulatory Compliance from Performance Claims

Regulatory compliance confirms a defined compliance scope. FCC certification, for example, confirms that the device meets electromagnetic interference standards. It does not validate therapeutic performance, engineering superiority, or specification accuracy.

What Compliance Confirms	What Compliance Does Not Confirm
The device meets defined electromagnetic safety or emissions standards	That the device performs better than competitors
The manufacturer submitted to a formal testing process	That listed Gauss, frequency, or waveform values are accurate
The device is authorized for sale in a given market	That the device delivers any specific health outcome

 

Compliance badges should not be used as proxy evidence for engineering transparency. They confirm a different kind of threshold entirely.

Cross-Check Unit Consistency and Conversion Clarity

A manufacturer specification sheet requires unit consistency. Standard units for PEMF specifications include Gauss, Tesla, microtesla (µT), and Hz. One Gauss equals 100 microtesla, and one Tesla equals 10,000 Gauss. These conversions should be clear and consistent throughout the sheet.

Are Gauss, Tesla, and microtesla used consistently? Is the conversion logic correct and readable? When a sheet switches units mid-document or presents unlabeled numbers, the inconsistency signals broader disclosure weakness. Unit sloppiness is rarely an isolated problem.

Use Disclosure Completeness, Not Headline Intensity, as the Primary Filter

Disclosure completeness is the stronger filter when comparing PEMF mats. A lower stated intensity with better context can still offer better transparency value than a high headline number with missing conditions.

Which disclosure gaps matter most? Missing measurement distance, hidden controller limits, and absent waveform timing. These three gaps undermine comparability more than any other combination. When evaluating specification sheets, weight these gaps heavier than the headline intensity figure. A mat with thorough disclosure at moderate intensity is a more trustworthy comparison subject than a mat with impressive numbers and no supporting context.

In practice, the most important PEMF specifications are the ones that remain meaningful after context is added back in. Measurement distance, controller behavior, waveform timing, and coil layout usually matter more than an isolated headline number because they determine whether the spec can be interpreted, verified, and compared under realistic operating conditions. A sheet becomes more decision-useful when it helps you understand how the device behaves, not just what maximum value can be printed in large type.

Final Decision Hierarchy 1. Filter by disclosure completeness first. 2. Classify each sheet as Transparent, Conditional, or Opaque. 3. Compare headline values only between sheets classified as Transparent. 4. For Conditional sheets, identify specific gaps before proceeding. 5. For Opaque sheets, request additional data before including them in any comparison.

 

FAQ

What counts as strong PEMF specification disclosure?

Strong disclosure means the specification sheet includes measurement context, operating context, and field behavior details together. The sheet discloses frequency with pulse detail, intensity with measurement distance and point, waveform with timing, coil layout with field distribution logic, and controller behavior with user-accessible parameters. Transparency is about comparability and verification rather than number inflation.

Why do measurement conditions matter in PEMF comparison?

Magnetic field readings change meaning when the measurement point and distance change. A Gauss number taken at the coil surface is not equivalent to one taken above the mat cover. Comparison without matched test conditions is weak because the numbers may reflect different measurement setups rather than different device capabilities.

How does measurement distance affect Gauss readings?

Magnetic flux density decreases rapidly as the measurement point moves away from the source. The same device can show different valid readings at different distances. A reading at the coil may be several times higher than a reading at the mat surface or a few centimeters above it. This is normal physics, not manipulation, but it makes undisclosed distance a comparability problem.

What is the difference between Surface Gauss and Effective Gauss?

These labels usually refer to different measurement contexts rather than the same reading under different names. Surface Gauss typically describes a reading at or near the mat surface. Effective Gauss typically describes a reading at a user-relevant distance. Both labels need a disclosed measurement point to be comparable.

Why is a frequency range not always enough to compare PEMF mats?

A frequency range can omit pulse repetition detail, preset logic, and controller limits. Two mats listing 1–99 Hz may deliver that range very differently: one with full user control in 1 Hz increments, another through locked presets that cycle through a handful of fixed values. Actual operating behavior matters more than a broad label.

What should a transparent PEMF controller description include?

A transparent controller description identifies whether settings are fixed, variable, preset-based, or automatic. It discloses which parameters the user can adjust, what each preset contains, and whether duty cycle and operating mode are visible to the user. This level of detail improves trust because it maps the specification range to real user experience.

Why does coil layout matter even when two mats list similar Gauss values?

Coil layout shapes field distribution, overlap, and uniformity. Two mats with similar headline Gauss values can produce very different coverage patterns if one clusters coils centrally and the other distributes them across the full mat area. Similar numbers do not guarantee similar field behavior.

Does FCC certification verify PEMF performance?

No. FCC-type compliance confirms that a device meets defined electromagnetic safety or emissions standards. It does not verify therapeutic performance, engineering accuracy, or specification transparency. Performance transparency still depends on measurement disclosure, not compliance badges.

What does duty cycle tell you on a PEMF specification sheet?

Duty cycle describes how much of the operating cycle the pulse is active versus off. A 50% duty cycle means the pulse is on for half the time. A 10% duty cycle means brief pulses with longer rest periods. It helps clarify waveform behavior and total energy delivery timing, making frequency and waveform disclosures more complete.

How can you audit a PEMF spec sheet when the manufacturer uses proprietary language?

Ask for measurement distance, waveform detail, controller behavior, coil layout, and test conditions in plain engineering terms. Request the actual Hz values, pulse timing, duty cycle, coil spacing, and Gaussmeter distance behind any branded label. Proprietary labels are only useful when backed by auditable parameters.
