Gauss Labs PEMF blog

You're comparing two devices. One lists 20,000 Gauss, the other lists 800, and the first looks twenty-five times stronger. It might be. It might also be weaker. Until you know what each maker measured, the two values can't be compared at all. This month we read the public product and testing pages of PEMF makers across the industry, from high-intensity coils to low-intensity mats, and logged how each one states its field strength. There is no shared convention. Most publish a single Gauss figure without saying how it was measured. A few publish a time-averaged value. At least one publishes…

You place a disc's center over a small joint, run the full session, and the relief comes up short. With a pancake coil, that's usually a placement miss. With a donut coil, the placement itself is the miss: you've aimed the field's weak spot at the joint. Two discs can share the same outer size and housing and still deliver very different fields. The coil wound inside sets the field's shape. A pancake concentrates its strength at the center. A donut spreads its strength into a ring and leaves a dip in the middle. A cross-section of a donut coil…

When your buyer reads the peak Gauss value on your spec sheet, they imagine that's for the entire surface of the accessory. They don't know that it's measured at one point, at one setting, directly on the accessory surface. Additional measurements let you show more of the accessory's characteristics in your documentation. A side-by-side diagram titled 'Peak Gauss alone doesn't provide the clarity needed to make an educated purchase.' On the left, under the heading 'On the spec sheet,' a gold block displays '7,000 G' as the Peak Gauss reading, called out as the highest reading at one point on…

When you place a disc on a knee for a 40-minute session and the patient feels less relief than expected, the instinct is to blame the device. Placement is the more likely culprit. A brochure can list peak Gauss without saying where the field is strongest. That value alone doesn't tell you where to place the disc. Two discs of the same outer size can deliver very different fields. A pancake coil peaks at the center; a donut coil peaks in a ring around the center. A cross-section of a pancake coil drawn beneath a field-strength curve. The spiral winding…

A smaller peak Gauss value can induce more in tissue. Faraday's law explains why. Two PEMF devices sit side by side on a shelf. One brochure says 7,000 Gauss. The other says 1,500 Gauss. The bigger value looks like the obvious winner. Faraday's law explains why it sometimes isn't. Tissue inside the body doesn't respond to the strength of a magnetic field. It responds to how fast that field is changing. A short, sharp pulse from a lower-peak device can induce more electrical activity in tissue than a tall, slow pulse from a higher-peak device. A magnetic-field-versus-time chart comparing two…

If you're about to spend a few thousand dollars on a PEMF device and the spec sheets all start to blur together, you don't need to become an expert in electromagnetics. You need six questions, and the discipline to ask all of them. Each question targets a value the brochure either left off or rounded into uselessness. Asked together, they replace marketing copy with a measured picture of what the device actually does. Question 1. Where was the peak measured? The reading depends on two things: how far the probe sits from the accessory surface, and where on the surface…

When you send equipment to a third-party lab, you should know what the process is before it starts. Ours is four steps over about three weeks, with regular updates throughout. Horizontal flow diagram of the four steps of a Gauss Labs certification engagement. Step 1, Schedule a Call: we review and discuss your device, accessories, and goals so we can write up a proposal. Step 2, Send Us Your Devices: we get your equipment queued up and ready for testing. Step 3, We'll Analyze Your Equipment: we'll test your equipment. Step 4, Review Your Results: we send your report, high-resolution…

If you've ever stood in front of two PEMF devices, compared their published values, and felt like you couldn't tell which one was better, you're not the problem. The values are the problem. You might be a chiropractor pricing a clinic system, an equine therapist comparing high-intensity machines, or a buyer for a wellness practice. What you need is a measured field map across the whole accessory surface, at every setting on the dial, on the unit you'll be paying for. Almost no spec sheet carries that. Product pages have the room, but the information just isn't included. Most companies…

If you design and build PEMF equipment, you already know your product works. Your buyers are starting to want more than your word for it. A third-party certification of measured performance gives them what they need. It also gives you an edge over manufacturers who can't produce one. Five years ago, a confident peak Gauss value on a glossy product page was enough to close most sales. Today, the buyers calling you are different. Some are clinicians burned on a previous purchase that didn't live up to its claims. Some are veterinary professionals comparing your machine against a competitor whose…
