ETCR Series Clamp-on Earthing Resistance Tester is widely used to measure ground resistance and loop resistance in electric power, telecommunications, meteorology, oil, construction and industrial electrical equipment. When measuring the circuit grounding system, without disconnecting ground deflectors, without auxiliary electrode, it’s safe and fast. It can measure the ground fault which difficult to be measured by traditional methods, because the ETCR Series Clamp-on Earthing Resistance Tester can measures the ground resistance and ground lead resistance.

Overview

Product Introduction
 
ETCR Series Clamp-on Earthing Resistance Tester is widely used to measure ground resistance and loop resistance in electric power telecommunications meteorology oil construction and industrial electrical equipment. When measuring the circuit grounding system without disconnecting ground deflectors without auxiliary electrode it’s safe and fast. It can measure the ground fault which difficult to be measured by traditional methods because the ETCR Series Clamp-on Earthing Resistance Tester can measures the ground resistance and ground lead resistance.
