4-Gems Disks Bio-Magnetic and Purple MediCrystal mats PEMF & EMF Test Data
Summary of PEMF and EMF testing of Purple MediCrystal Amethyst Agate PEMF Photon mats and 4-Gems Disks Amethyst Tourmaline Jade Agate Ivory Croco Bio-Magnetic mats
Purple MediCrystal Amethyst Agate PEMF Photon mats and 4-Gems Disks Amethyst Tourmaline Jade Agate Ivory Croco Bio-Magnetic mats feature the same Pulsed Electromagnetic Fields System.
These mats PEMF function allows selecting 4 Hz, 8 Hz, 10 Hz, or 14 Hz frequency of magnetic pulsation. (1 Hz = 1 pulse per second)
The mini mat has two PEMF coils; the midsize mat comes with six coils, professional and single-sized mats with eight PEMF coils positioned across two parallel lines extending from the feet zone to the logo area mat.

PEMF for different frequency settings over one coil
Researched by C.D. Lytle, Ph.D., in February 2020
Mat: Purple MediCrystal Amethyst Agate PEMF Photon Mini Mat 20"x32."
Mat settings: PEMF On, Heat, and Photo Off
Controllers: L-40PV-6 for 10 Hz or L-40PVA-6 50 for 4, 8, and 14 Hz 50 Gauss pulses
Magnetometer: EMF Tester PCE-EMF823. The quoted range is 30-300 Hz. However, careful, independent comparison indicated it 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.* Distance from PEMF coil to mat surface is unknown.

*The sensor of the magnetometer is located in the center of the top end of the meter. When the meter was placed horizontally, the sensor was actually 5/8” above the mat surface.
Observations:
- Measured PEMF values were not significantly different for the different pulse frequencies. They were approximately 7.5% of the PEMF 50 Gauss rated value, presumably because of the distance and materials between the PEMF coils and the magnetometer sensor.

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.

* No readings over the mat were at or above 0.2 mGauss, the limit of detectability of the meter, except the “hot spots.” In addition, when the heat setting was reduced, the readings over the “hot spots” immediately dropped to undetectable.
Conclusions:
- Three ‘hot spots’ were located, all along the centerline of the mat.
- Two such ‘hot spots’ were approximately over the presumed PEMF coils.
- The third ‘hot spot’ was between the PEMF coils near the very low PEMF when the PEMF was turned on.
- The ‘hot spots’ relate to the safety sensors or bimetal switches functioning.
