The PF5 is an accurate, easy to use, pocket size EMF meter. The PF5 measures magnetic AND electric fields from power lines, house wiring, and from appliances at home and at work. It measures magnetic fields in milliGauss (mG) units, and unlike most gauss meters it also measures electric fields in V/m units. The PF5 measures frequencies from 20 Hz to well over 50 kHz. This huge frequency bandwidth (not found in most EMF meters) enables the PF5 to measure EMFs from higher frequency electric and magnetic fields emitted by VLF appliances, like induction cooking hobs, solar-panel inverters, energy-saving compact fluorescent (CFL) lamps and some LED lights. These fields can cause headaches and eye problems among other adverse health effects. These new higher frequency appliances are of concern since the currents they induce in your body are proportional to frequency. Induction hobs, in particular, induce some of the highest internal electric currents in your body in the VLF frequency range, which have been shown to significantly affect the nervous system, so it is advisable to limit your exposure to these VLF fields. The Swedish National Energy Department issued an advisory warning that schools, playgrounds, and day-care centers should not be sited near power lines, and that children should not be subjected for long periods every day to AC (50-60 Hz) magnetic fields over 3.0 mG. The PF5 can accurately measure this. The PF5 measures magnetic field strength from 0.2 to 20.0 milliGauss (mG), and electric field strength from 5 to 200 V/m. Readout is using a column of LED lights. It does not measure magnets, nor RF fields like mobile phones or WiFi. The PF5 is single-axis, so it is necessary to rotate the meter to measure the field. Includes instructions, battery, soft carry-case. Lightweight and very compact (4½ " x 2¼ "x ¾"). The PF5 is manufactured by EMFields in UK, known for accurate, high-quality home measurement instruments, with a 2-year warranty.
