ETCR Series Earth Clamp Meter

ETCR series Earth Clamp Meter is widely used in the grounding resistance measurement of electric power, telecommunications, meteorology, oilfield, construction and the industrial and electrical equipment.

The measurement does not require disconnecting the grounding wire, need no auxiliary electrode. It is safe, fast and simple in use. It equips long jaws or round jaws. Long jaw is particularly suitable for the occasion of grounding with the flat steel. It also be able to measure the leakage current and the neutral current in the grounding system.
