Earth testers: analogue and digital

Earth resistance is not earth-leakage protection. A panel earth-leakage relay watches residual current. An earth tester measures the resistance of an electrode or a loop. Shortlist the tester that matches the method in your procedure.

WACO’s hand-driven earth tester is the analogue, generator-driven style still used where a site wants a mechanical instrument. WACO-DET is listed as the DET series digital earth resistance tester. The catalog note says that catalogue card prints DET LOW, DET MID, DET HIGH and WACO-4100 on the one instrument, so confirm which range you need when you quote.

Metravi ERT-1501 is listed as a digital earth resistance tester with kit. Metravi CET-01 is listed as a clamp-on ground resistance tester, for a method that clamps the electrode instead of driving spikes. Kyoritsu KEW 4105A is listed as an earth tester for 3-pole and 2-pole earth resistance, designed to IP54.

Metravi PRO ERT-1602 is listed as an earth resistance and soil resistivity tester. Use it when the job is soil resistivity, not only a single electrode reading. Send the method (spikes, clamp, or soil) with the part number to Vishal Electricals in Chickpet.
