An EMF meter can measure AC electromagnetic fields, which are usually emitted from man-made sources such as electrical wiring, while gaussmeters or magnetometers measure DC fields, which occur naturally in Earth's geomagnetic field and are emitted from other sources where direct current is present.

Is EMF bad for your health?

Despite extensive research, to date there is no evidence to conclude that exposure to low level electromagnetic fields is harmful to human health.

What is an EMF tester?

An electromagnetic field test measures the amount of electric, magnetic, and electromagnetic exposure a product emits to its users, including static, extremely low frequency and radio frequency fields. There are different regulatory limits for occupational and general public exposure.
