Three PEMF certifications went on the public Gauss Labs registry in August. Here is what went up, why one device and two accessories produced three separate listings, and how to check a certification badge yourself in about a minute.

Two PEMF discs can look identical on the outside and still put their strongest field in completely different places. Our 3D field viewer is now open to anyone, with a page for each of the four common coil types built from a real measured scan.

New in the 3D viewer: slice the measured field open with a movable cross-section, scrub the pulse to any moment, and set a full-scale person on the mat to see depth and coverage.

Every example report now includes an interactive 3D viewer of the measured field: a field dome for reach, a new topographic map for strength, and the device's real pulse.

A PEMF field does not stop at one line. It fades from the center, and two boundaries, the strong core and the usable edge, describe what you actually get.

June's newly certified PEMF products: the CELLER8 device and two accessories, each active and verifiable on our public registry.

For competition horses, the FEI caps PEMF field strength at 1,000 Gauss. Here's what the limit means, and how a certification shows which device-and-accessory pairing stays under it.

Frequency is one of the few PEMF specs you can actually use, once you read the band name for what it is: a pulse rate, separate from strength and from the pulse edge. Here's what it tells you, what the devices we've measured actually run, and how to use it.

On a single device, swapping the coil changed the peak field from 22,410 to 8,670 Gauss, and the lower-peak coil put out nearly twice the total field. The accessory, not the device, sets what you get.

Rise time, fall time, and slew rate describe what a PEMF pulse does in its few microseconds. Here is what each one means, measured on a real device.
