Guide to Buying an EMF Meter
The term ‘EMF’ has several meanings. In this article we look at the three common sources of EMF radiation and the best professional EMF meters for measuring each type.
The term EMF is used rather loosely, since there are electric fields, there are magnetic fields, and many types of electro-magnetic fields. Both electric fields and magnetic fields can be static or dynamic - like the alternating current in our power mains.
The below tables shows examples of these different fields and the best EMF meter for each type.

None of the fields above can be seen. The effects of some electric fields can be felt, like hair lifting or sharp stings from static electricity discharges, but most EMFs are invisible and undetectable by any human sense. We have divided them into the groups above, because each type of field requires a particular type of EMF meter to detect its presence.
Overview of the Wavecontrol SMP3 EMF Meter
SMP3 EMF Field Strength Meter
- Broadband measurements DC - 60 GHZ With RMS and isotropic field probes.
- This ONE meter will do all EMF measurements with the correct probe selected, including Electric and Magnetic components.
- Spectrum analysis DC - 400 KHZ real-time FFT.
- Weightes Peak Method (WPM) real-time comparison in terms of % with the selected limits.
- Assessments in accordance with international standards: ICNIRP, IEC, EN, IEEE, etc.
- High performance GPS integrated in the instrument.
- USB and fibre optic communication PC software included.
Wavecontrol EMF Probes
By selecting the probe to suit your application, the SMP3 meter will cover from DC-60Ghz with E&H, E, or H response as per the table following. When you need to add an additional frequency range, you simply order a new probe. No need to buy a whole new meter!
We have specific probes for measurement of Wifi and Mobile phone bands. For advice on probes give our friendly team a call on 1300 236 682.

Weighted Peak Method up to 10MHz
RF transmission is complex seldom comprising a single spectral component, therefore using RMS values for reference exposure levels is unsuitable for this purpose. The WPM method better emulates physical and biological effects on humans and has been chosen as the reference assessment method for non-thermal effects in the frequency range 1 Hz to 10 MHz.
Implementing the WPM in measurement devices has engineering challenges and is generally limited to 400kHz.
The Wavecontrol SMP3 has implemented the WPM up to 10MHz and now fully complies with LF standards as well as being unique in the market.
