Dual-field EMF detector

The TeKit GM3120 is a handheld digital meter that measures electric-field strength and magnetic-flux density simultaneously. It covers 1 to 1999 V/m for electric fields and 0.01 to 19.99 T for magnetic fields. A 3½-digit LCD shows the readings, and a sound-light alarm activates when either value exceeds its preset threshold. The unit runs on a single 9 V battery.

Home owners and hobbyists.

This meter suits anyone wanting a quick indication of electromagnetic levels around appliances, wiring or outdoor sources. The automatic radiation-assessment prompt and one-key data-lock make spot checks simple. Buyers who need traceable calibration certificates or measurement uncertainty budgets for regulatory reporting should look at laboratory-grade instruments instead.

Alarm thresholds at 40 V/m and 0.4 T

The instrument triggers its audible and visual warning as soon as the electric field rises above 40 V/m or the magnetic field exceeds 0.4 T. These fixed limits are the primary decision point for safety-oriented users. If your application requires different trigger levels or continuous data logging, this model will not meet that need.

Questions about this item

What does the 1999 V/m upper limit mean when I am scanning a room?

The meter will show electric-field strength up to 1999 V/m; anything stronger simply reads at the top of the scale.

How does the 5 Hz – 3500 MHz bandwidth affect what the GM3120 can detect?

It covers low-frequency mains fields through to common RF sources such as Wi-Fi and mobile signals, but not millimetre-wave bands.

What power source does the GM3120 need to operate?

A single 9 V battery powers the unit; the DC polarity indicator helps confirm correct insertion.
