DET14C EARTH CLAMP

Megger Earth & Ground Resistance Tester

The Megger earth and ground resistance tester measure a 1.5kΩ absolute maximum resistance and having the CAT IV 600V safety category. It is calibrated by UKAS. This 4-pole earth tester is used to measure soil resistivity and resistance of earth rods and associated installations. It is supplied in a hard carry case together with auxiliary stakes and cables. An ICLAMP selective clamp is available separately and when used with the DET4TC allows the testing of an earth rod without the need to disconnect from the system. A VCLAMP is also available separately, which when used in conjunction with ICLAMP allows stakeless measurements to be made in situations where driving auxiliary stakes is not practical. It has a rechargeable battery-powered 4-terminal tester with selectable test frequencies, greater measurement sensitivity and attached rod technique and stakeless measurement capability.
