Ground pile clamp earth resistance tester also name Loop resistance tester,used for grounding resistance test.
This instrument uses 2.4-inch color screen design, with clamp resistance, three or four wire resistance, AC voltage, current measurement functions, and also has data storage, data access, alarm, automatic shutdown and other functions.
This meter is beautiful and high-grade, wide range, high resolution, convenient operation, easy to carry, accurate, reliable, stable performance, strong anti-interference ability.It also has a shock-proof, dust-proof, and moisture-proof structure. It is a commonly used and indispensable instrument for telecommunications, electric power, meteorology, computer rooms, oil fields, electronic mechanical installation and maintenance, and industrial enterprises that use electricity as industrial power or energy. It is suitable for measuring grounding resistance of various telecommunications, electricity, meteorology, computer rooms, oil fields, power distribution lines, transmission lines of iron towers, gas stations, factory grounding grids, lightning rods, etc.
The ground-pile clamp ground resistance tester is controlled by a microprocessor and can accurately detect ground resistance. It uses fast filtering technology to minimize interference. At the same time with data storage and data upload functions.
