This Dirty Electricity Monitor Line EMI measures electromagnetic interference in a single-phase AC power line.
No battery needed as it plugs into a wall socket. It immediately displays total line noise in millivolts (range 1999 mV, resolution 1 mV) in the frequency range 10 kHz–10 MHz (the frequency limits at which sensitivity is half of the maximum sensitivity). A speaker plays the sound of the EMI, with amplitude demodulated, in order to identify EMI sources such as AM or shortwave radio frequency.

The Line EMI Dirty Electricity Monitor measures electromagnetic interference in a single-phase AC power line. Its OLED screen displays AC voltage and noise voltage. The speaker emits a sound that increases according to the intensity of the frequency, the more interference the louder the sound.
The EMI monitor can be used to detect dirty electricity levels at home and in other environments. Dirty electricity can tamper the correct functioning of sensitive electrical equipment. Plus it emits electromagnetic fields (EMF) and has been associated with a wide range of health issues. The more dirty electricity on your wiring, the more EMF in your space.
The Line EMI Dirty Electricity Monitor is also a great tool to test dirty electricity filters and see the difference they make in reducing unwanted electrical noise. Hear the noise decrease as dirty electricity filters are set up.
This meter is easy to use as you simply have to plug it into a power socket and the electronic display will show readings in millivolts (mV), a standard electrical unit of measure.
The dimensions of the device are 132 x 91 x 41mm and it weighs 150g. It comes with a detachable two-core power 0.8 m-length cord and it plugs directly into an electrical outlet.

Try the monitor with and without your filters to see what difference they really make!
Simply plug the meter into electrical outlets to find out how much dirty electricity is present on nearby wiring.
Ideally, dirty electricity (EMI) levels should be below 25 millivolts (mV). Levels between 25 and 50 mV are marginal and should be reduced if possible. Levels above 50 mV are undesirable and steps should be taken to lower them.
The TriField Dirty Electricity EMI Meter can be used to measure dirty electricity on 50/60 Hz AC circuits with a voltage anywhere between 100 V and 240 V.
The meter is compatible with 50/60 Hz AC electrical circuits with a voltage anywhere between 100 V and 240 V. This means it can be used in many countries around the world with the correct adapter. This will ship with a UK adapter.
