GOZ-2572 Earth Resistance Tester
GOZ-2572 Earth Resistance Tester was designed according IEC, ISO, BS, VL, JIS, etc standards. Earth resistance is an important index to measure the safety performance for all kinds of equipments. It tests the earth resistance under current (25A or 10A), avoid to hurt people if the insulating property reduced (or broken).
Alternative Name
Digital ground resistance tester, ground resistance tester
