Product Introduction
Clamp Ground Resistance Tester, also known as Loop Resistance Tester, is used for testing ground resistance. This instrument features a new black luxury screen design, simultaneous display of resistance and current, and also includes functions such as data storage, data review, alarm, and automatic shutdown. The unit is aesthetically pleasing and high-end, with a wide range, high resolution, easy operation, portability, accuracy, reliability, stable performance, and strong anti-interference capability. It also has a shockproof, dustproof, and moisture-proof structure, making it an essential and commonly used instrument in telecommunications, power, meteorology, computer rooms, oil fields, mechanical and electrical installation and maintenance, and industrial enterprises that use electricity as an industrial power or energy source. It is suitable for measuring the ground resistance of various telecommunications, power, meteorology, computer rooms, oil fields, power distribution lines, tower transmission lines, gas stations, factory grounding networks, lightning rods, etc.
Clamp Ground Resistance Tester is controlled by a microprocessor to accurately detect ground resistance. It uses fast filtering technology to minimize interference. It also includes functions such as data storage and data upload.
