Metrel MI3123 Earth / Clamp Tester Details

The Metrel MI 3123 SMARTEC Earth Tester and Clamps is a remarkable earth spike resistance tester with the ability to perform 2-wire and 3-wire earth spike testing, and 4-wire soil resistivity testing.

With the optional A1018 and A1019 current clamps, the unit can perform one clamp resistance measurement, two clamp (no contact) earth spike testing and TRMS current measurement up to 20A.

The rechargeable unit has configurable limits which can provide automated pass/fail evaluation of test results.

The large bright LCD display, 1.85kg lightweight tester and built in help screens make this earth tester an easy to use wise investment.

This tester also has optional downloading via RS232 or USB and CAT IV protection rating. The Metrel MI 3123 is ideal for electricians who require a professional earth tester with clamps.
