Clamp-On Ground Resistance Tester

Type: ZC-412
    ZC-412 Clamp-On Ground Resistance Tester 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.
    ZC-412 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.
