EMI Power Line Analyser

The Trifield EM100 is a single-phase AC power-line meter that measures electromagnetic interference on building wiring. Its bright OLED screen and amplitude-demodulated audio let you identify noise sources immediately. The unit plugs directly into a mains socket with no switches or knobs to configure.

Homeowners and technicians checking supply quality

Suited to anyone who wants a quick, plug-and-play view of EMI levels in a house, office or workshop. Not for users who need logging, data export or multi-phase analysis, because the device provides only a live readout.

100 kHz to 10 MHz measurement bandwidth

The EM100 covers a 100 kHz to 10 MHz bandwidth, which determines the range of conducted emissions it can detect. This single figure tells you whether the analyser matches the noise frequencies you are investigating.

Questions about this item

Does the EM100 come with any probes, cables or accessories in the box, or must they be purchased separately?

The EM100 is a self-contained plug-in module with a built-in OLED screen and audio output, so no extra probes, cables or accessories are required for basic EMI measurement.

The supplier title mentions a single EM100 model — are there different versions or capacity options to choose from?

Only one EM100 model is listed; there are no alternative versions, bandwidth tiers or capacity options to select.

What does the headline 100 figure represent when the EM100 is plugged into a real mains circuit?

The 100 figure is the model identifier; the instrument displays real-time EMI amplitude on its OLED screen and provides demodulated audio to help locate noise sources on the power line.
