Summary of PEMF and EMF testing of ThermoGem mats

ThermoGem Amethyst Tourmaline Jade PEMF Photon mats, belts, and vests and MediCrystal® Bio-Magnetic Amethyst Tourmaline V-mats feature the same type of Pulsed Electromagnetic Fields System.

Their PEMF function allows adjusting frequencies manually with a dial in the range between 1 and 30 Hz, with a 1 Hz increment.

Also, you can select 1 of 13 programs of different lengths from 1 to 12 hours, automatically changing frequencies as per set algorithms.

The mini mat has three PEMF coils, the midsize mat comes with six coils, a professional one with eight coils, and the single-size mat has ten PEMF coils positioned across two parallel lines extending from the feet zone to the logo area of the mat.

PEMF for different frequencies over one coil

Researched by C.D. Lytle, Ph.D., in February 2020

ThermoGem Amethyst Tourmaline Jade PEMF Photon Compact Mat 22"x48".

Mat settings: PEMF On, Heat, and Photo Off

Controller: H-60PVA, 50 Gauss pulses at 0-30Hz (variable)

Magnetometer: EMF Tester PCE-EMF823. Although the quoted range is 30-300 Hz, a careful, independent comparison indicated the PCE-EMF823 was accurate down to at least 8Hz.

The range used: 0 - 20000 mGauss

The magnetometer was laid horizontally on the mat to reduce the effect of uneven surface; the sensor was 5/8” (1.6 cm) above the mat surface.* Distance from PEMF coil to mat surface is unknown.

*Meter was placed on the centerline of the mat and 8.25 inches from the top of the heated portion.

Observations:

Measured values were essentially constant for the different frequencies and roughly 12.5 % of the 50 Gauss rated intensity.
Measured values varied little while the frequency changed over a factor of 30.

Magnetometer: PCE-EMF823. The range used: 0 - 20000 mGauss

The magnetometer was laid horizontally on the mat to reduce the effect of uneven surface; the sensor was 5/8” above the mat surface. Measurements over the peaks were also made with the meter held vertically with the sensor directly against the mat surface.

Observations:

Measurements over coils on mat surface were 7.6-8 Gauss (~15% of rated 50 Gauss coils).
PEMF intensity dropped more than 70% within 2.75 inches along the centerline.

* No readings over the mat were at or above 0.2 mGauss, the limit of detectability of the meter, except at the noted locations.

Observations:

Four locations were located.
Three locations were over the PEMF coils and were detectable with or without the heat functioning.
The remaining location was only detectable when the heat was ON. It was near the third PEMF coil but closer to the left side of the mat.
The ‘hot spots’ relate to the safety sensors or bimetal switches functioning.

ThermoGem Inc is grateful to C.D. Lytle, Ph.D., for data collection, testing the mat, meticulously researching and preparing this report!
