Digital Clamp on Earth resistance Tester, DECT Series measures earth resistance using clamp on technology. Clamp on is a relatively new method of determining the quality of a ground system. DECT Series can measure Earth Resistance, earth bonds measurement & also measures AC leakage current. It's actually recommended to use it on sites where there are multiple grounds placed in parallel and not required to isolate the ground rod. Simply clamp around the conductor or earthing strip and measure the Earth Resistance fast and accurately. The unique big jaw is particularly suitable where grounding is done by flat steels or copper strips. It has low battery indication & data hold facility within built memory storage of up to 99 test results. DECT Series has got the double insulation level and is protected from external magnetic & electric fields.
