ETCR clamp ground resistance tester is widely used in grounding resistance measurement and loop resistance measurement in power, telecommunication, meteorology, oilfield, construction and industrial electrical equipment. When measuring a grounded system with a loop, it is not necessary to disconnect the ground deflector, and no auxiliary electrode is required. It is safe and fast. The ETCR Clamp Ground Resistance Meter measures ground faults that cannot be measured with conventional methods and can be used in applications where traditional methods cannot be used. The Clamp Ground Resistance Tester measures the combined value of the ground resistance and the ground lead resistance.

1. Ground resistance measurement, loop resistance measurement.
2. The major breakthroughs in ground resistance testing technology and non-contact measurement are fast and safe.
3. When measuring a grounded system with loop, it is not necessary to disconnect the ground deflector and no auxiliary electrode is needed, saving time and effort.
4. Clamp-type grounding resistance meters can measure ground faults that cannot be measured with traditional methods and can be used in applications where traditional methods cannot be measured.
5. Sound and light alarm function.
