Some sensitive individuals will be able to feel their iMRS mat, pillow, and probe working. Others will only be able to tell their iMRS is working by judging the long-term effects they experience in their health. If you fall into the second group, there is a simple way to test your iMRS.
A Gauss Meter (sometimes called EMF meter) is a simple electronic
device that is designed to alert you to the presence of EMF fields. You turn it on. Then, turn on your iMRS and it will show you the PEMF in action. They are inexpensive. Check Amazon and look for "magnetic wave testers" or "gauss meters".
Any gaussmeter will work as long as it will measure the intensities and frequencies the iMRS produces. Make sure the unit you buy can measure:
Any electronic device can break from time to time. It happens. A gauss meter is the best way to ensure that your PEMF system is operating correctly.
