Top 8 EMF Detectors of 2018 | Video Review
This is why EMF detectors are so important. EMF detectors indicate the presence of electromagnetic frequency through the use of one or more receiving antennae that measure differing AC or DC electrical currents. When EMF is present the meter signals the user. The strength of the reading is a direct indicator of the strength of the frequency.
EMF measurement - Wikipedia
An EMF meter is a scientific instrument for measuring electromagnetic fields (abbreviated as EMF). Most meters measure the electromagnetic radiation flux density (DC fields) or the change in an electromagnetic field over time (AC fields), essentially the same as a radio antenna, but with quite different detection characteristics.
