EMF Detector AC gaussmeter, electric field meter, RF field strength meter combined in one electromagnetic instrument. An excellent tool for electricians or those curious about EMF fields.
Meter combines all the features needed for fast, accurate measurements of electromagnetic fields.
It independently measures electric field and magnetic field, and is properly scaled to indicate the full magnitude of currents produced by each type of field inside a conductive body. It has significant sensitivity at 100,000 Hz, well past the 17,000 Hz horizontal scan of video displays. In addition, the magnetic setting and the electric setting measure true magnitude, a feature found elsewhere only in more expensive meters. If you hold the meter in the center of a room and tip it to various angles, the magnetic reading will stay approximately the same regardless of which way you tip or rotate it. The electric reading is similar, although the presence of your body alters the actual electric field, so readings will vary more.
