In this video Guy Hudson talks about the Electric and Magnetic Power Frequencies Meter.
The PF5 is EMFields newest power-frequencies detector. The PF5 measures electric and magnetic EMFs from house wiring, including those from appliances at home at at work. The PF5, unlike most EMF meters on the market, also measures frequencies in the range from 20 Hz to well over 50 kHz. This enables the PF5 to measure the higher frequency electric and magnetic fields emitted by induction cooking hobs, solar-panel inverters, ‘energy-saving’ compact fluorescent (CFL) lamps and some LED lights.
These are amongst the most concerning new sources of our electromagnetic field exposures as the currents they induce in your body are proportional to the frequency. So a magnetic field at 25000 Hz (25 kHz) will induce 500 times more current in your body compared with same strength of field at 50 Hz. Induction hobs, in particular, induce some of the highest internal electric currents in your body in the VLF frequency range. Such currents have been shown to significantly affect the nervous system.
The PF5 is an easy to use, pocket sized, accurate, power-frequencies meter which is ideal for carrying around. It measures both electric and magnetic fields and is available labelled in either international microtesla (µT) units or in milliGauss (mG) units for America, Canada and Australia etc.
