The PF5 Pocket Power Frequencies Meter (ELF & VLF)
The PF5 is the newest EMF power-frequencies detector. The PF5 measures electric and magnetic EMFs from house wiring, including those from appliances at home and 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) bulbs and some LED lights.
These are among the most concerning new sources of our electromagnetic field exposures as the currents they induce in our bodies 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 sensitive, accurate and easy to use, a pocket sized power-frequencies meter which is ideal for carrying around. It measures both electric and magnetic fields. The PF5 power-frequencies meter was designed using 25 years experience of EMF measurements and research. Although some specialist meters also measure VLF frequencies, they tend to be expensive. The PF5 is an affordable meter that makes it easy to measure these new major sources of EMF exposure.
Induction hobs use VLF magnetic fields to induce high currents in iron and steel pans which then internally heat the metal. They are very energy-efficient, but some of the VLF fields leak out around the base of the pan and expose the person doing the cooking. A 2012 study that measured 16 induction hob units found that most could exceed even the very high ICNIRP levels . Induction hobs can expose you to some of the highest exposures that most people will experience in their lives.
Not only can the PF5 measure those magnetic fields, but the PF5 can also measure VLF electric fields from other modern devices like energy saving CFL light bulbs. These electric fields can cause headaches and eye problems among other adverse health effects.
Most non-sine-wave solar power inverters generate high levels of VLF electric and magnetic fields that the PF5 can also measure while most power-frequency EMF meters will ignore them.
Easy to use
To turn it off, push and hold for about 2 seconds. It will also automatically switch itself off after about 5 minutes use to save the battery power.
The PF5 Pocket Power Frequencies Meter comes complete with a quality pouch, including user notes.
Press the button once to activate the PF5. It will measure the magnetic fields and the right-hand scale is indicated by a green LED.
Press the button again to change to measuring electric fields. Each short press will cause it to swap between electrical and magnetic measurements.
The internal electric field sensor antenna is inside the top end of the case. The large magnetic field coil is fairly central in the top half of the back of the instrument. Turn the PF5 for the highest reading.
The LED scales are easy to read and use and are color-coded for reasonable precautionary use. When two LEDs are both lit next to each other, then the exposure level is halfway between the two. Technical specifications
