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.

The Acousticom 2 presents RF measurements as an audio signal, with LEDs and an alarm at high levels of RF (you can also switch the sound off if you prefer to be less obvious when taking readings). With simple controls, easy to read results, but still using the same advanced microwave detector as our Acoustimeter, this instrument is perfect for those on a budget. It is smaller and lighter than the Acoustimeter, and comes in its own carry pouch.
