earth resistance tester, ground clamp meter, ground clamp resistance tester
ETCR2000 series Ground Clamp Meter is a major technological breakthrough in traditional grounding resistance measurement. It is widely used in the grounding resistance measurement of electric power, telecommunications, meteorology, oilfield, construction and the industrial and electrical equipment.
ETCR2000 series Ground Clamp Meter, in the measurement of a grounding system with loop current, does not require disconnecting the grounding wire, and need no auxiliary electrode. It is safe, fast and simple in use.
ETCR2000 series Ground Clamp Meter can measure out the faults beyond the reach of the traditional methods, and can be applied in the occasions not in the range of the traditional methods. ETCR2000 series Earth Ground Clamp Meter can measure the integrated value of the grounding body resistance and the grounding lead resistance.
ETCR2000 series Ground Clamp Meter are equipped with either a long clamp or a round clamp, as indicated in the figure below. A long clamp is particularly suitable for the occasion of grounding with the flat steel.
In addition, ETCR2000C Earth Ground Clamp Meter is also able to measure the leakage current and the neutral current in the grounding system.
