What are typical EMF readings inside the Ultra Low 2 person model?
Hello John, you see two bits of information noted in the SPECS section of product page.
1) Ultra Low EMF = Less than 3 milligauss
2) Our tests showed an actual level of 1 to 2 milligauss right on the heater surface.
EMF decreases exponentially as you increase the distance from the source, so those near zero readings right on the surface of the heater are really as good as is physically possible.
