The Earth Grid Tester is an instrument that uses heterodyne multi-power supply technology to measure the grounding resistance of the earth grid.
【Main Features】
The Earth Grid Tester adopts the heterodyne multi-power supply method, combined with software and hardware filtering technology, to improve anti-interference capability; through computer data processing, it eliminates interference between measuring leads, ensuring high measurement accuracy; low wiring labor, no need for high-current wires; and it is small in size and light in weight; the LCD Chinese display directly gives measurement results, with printing function.
