Description
The PF5 is our 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.
Which one should I choose?
It’s up to you – whilst the scales are different, both measure the same thing. It’s a little like a ruler measuring in cm or inches – it measures length, but the scale you are most comfortable with is the one you should use.

Easy to use
Carry pouch supplied
Our PF5 Pocket Power Frequencies Meter comes complete with a quality pouch, including neat folded 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.
We show electric field measurements, at face height when standing, of two different light bulbs – a 60 Watt incandescent bulb and an equivalent light-power ‘energy-saving’ compact fluorescent lamp (CFL). The electric fields are 3 times higher, but because of the much higher frequency the induced signals in your body will be in the order of 1500 times greater.
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 LED scales are easy to read and use and are colour-coded for reasonable precautionary use. When two LEDs are both lit next to each other, then the exposure level is halfway between the two.

I bought the PF5 because of its capability of measuring an extended range of frequencies, into the VLF range. Not many handheld power frequency meters measure both ELF and VLF frequencies.
I would recommend the PF5 to anyone who is concerned about their exposure to electric and magnetic fields.
The meter is very easy to use and great for assessing levels of electric fields from household wiring as well as a host of other sources.
It’s surprising how high the fields can be from the lighting circuits alone. How many people know what they’re exposed to in their own homes on a daily basis? No wonder so many people are ill.

I bought this meter together with the Acousticom 2 and started measuring my living space. Turns out that I was unnessarily exposed to electric fields for much too long from…
– an unearthed powerline adapter
– an unearthed Apple Macbook charger
– a fluorescent bulp in the lamp above my kitchen table
We live in the electromagnetic age (see Martin Blanks book “Overpowered”) and I believe that it is the duty of every responsible husband and father to make sure that he and his beloved ones are not exposed to electric and magnetic fields as well as radio frequencies where this can be avoided. To avoid it in the outside world is difficult but at home where you sleep and rest you can do a lot.
This meter helps you to understand to what you are exposed so that you can start to fix things.

Very pleased with this unit. It put our minds at rest when we were searching for properties. I would recommend this item if you are house hunting.
