The TriField EMF Meter is an AC gaussmeter, AC electric field meter, and radio frequency (mobile phones, WiFi etc.) meter in a single unit, that combines all the features needed for fast, accurate measurements of electromagnetic fields (EMF). In addition to standard AC measurement modes, a special frequency weighted mode will properly scale the magnetic and electric measurements to indicate the full magnitude of currents produced by each type of field inside the human body.
