Dirty Electricity Line EMI Monitor
The Line EMI Monitor measures electromagnetic interference in a single-phase AC power line. It plugs into a wall outlet (mains socket) and requires no battery. 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 the EMI source (such as an AM or shortwave radio station vs a motor vs an electric arc).

What is a recommended EMI level?
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.
What voltage does this work with?
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.
Will this work in my country?
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.
What are the dimensions of the device?
5.2 in x 3.6 in x 1.6 in; 132 mm x 91 mm x 41 mm
