Clamp ground resistance tester, also known as loop resistance tester, is used to test ground resistance. This instrument uses a new black luxury screen design, the resistance current is displayed on the same screen, and it also has functions such as data storage, data review, alarm, and automatic shutdown. The whole machine is beautiful and high-grade, with a wide range, high resolution, convenient operation, convenient carrying, accurate, reliable, stable performance and strong anti-interference ability. Moreover, it has a shock-proof, dust-proof and moisture-proof structure. It is a common and indispensable instrument for telecommunications, electricity, meteorology, computer rooms, oil fields, electromechanical installation and maintenance, and industrial enterprises that use electricity as industrial power or energy. It is suitable for measuring grounding resistance of various telecommunications, electric power, meteorology, computer room, oil field, power distribution lines, tower transmission lines, gas stations, factory grounding grids, lightning rods, etc.
The clamp ground resistance tester is controlled by a microprocessor and can accurately detect ground resistance. It uses fast filtering techniques to minimize interference. Simultaneous data storage and data upload functions.
