Product Introduction
Stake-Type Clamp Ground Resistance Tester, also known as Loop Resistance Tester, is used for testing ground resistance. This instrument features a new 2.4-inch luxurious color screen design, with functions including clamp resistance, three or four-wire resistance, AC voltage, and current measurement. It also includes data storage, data review, alarm, automatic shutdown, and other functions. The entire 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, as well as industrial enterprises that use electricity as an industrial power or energy source. It is suitable for measuring ground resistance in various applications such as telecommunications, power, meteorology, computer rooms, oil fields, power distribution lines, tower transmission lines, gas stations, factory grounding networks, lightning rods, etc.
Stake-Type Clamp Ground Resistance Tester is controlled by a microprocessor to accurately detect ground resistance. It uses fast filtering technology to minimize interference and includes functions such as data storage and data upload.
