Megger DET20C Clamp-on Earth Resistance Tester

MEGGER DET20C Clamp-On Earth Resistance Tester

Easy, fast clamp-on operation – No rods or cables necessary. Measures ground resistance from 0.025O to 1550O. Measures ground leakage current from 0.2mA to 35A. Auto ranging with high and low alarms. Automatic self calibration. Extensive data storage and USB data download for later analysis (DET20C).

The Megger models DET10C and 20C measure earth/ground resistance and current flow using clamp-on technology. The instruments induce a test current into the system without the need to disturb existing connections. Either unit is a useful addition to the more traditional methods of earth/ground resistance testing that may require disconnection and the use of stakes or ground rods. Simply clamp around the conductor or stake/rod and measure the resistance to ground fast and accurately.

The DET10C and 20C can also be used to measure earth/ground resistance in multiple loop installations without disconnecting the earth or ground. This allows the user to perform the test quickly and easily in total safety, with the added convenience of having a single point of measurement to read the earth/ground resistance
