-Pile clamp ground resistance tester, also known as loop resistance tester, used to test ground resistance. This instrument uses a brand new 2.4-inch luxury color screen design, with clamp resistance, three-four-wire resistance, AC voltage, current measurement functions, and has data storage, data access, alarm, automatic shutdown and other functions.
-The whole machine is beautiful and high-grade, wide range, high resolution, easy to operate, 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 common and indispensable instrument for telecommunications, electric power, meteorology, computer rooms, oil fields, electromechanical installation and maintenance, and industrial enterprises that use electric power as industrial power or energy.
-Suitable for measuring the 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 resistance tester of the pile clamp is controlled by a microprocessor, which can accurately detect the ground resistance. It uses fast filtering technology to reduce interference. It also has data storage and data upload functions.
Welcome and I wish you a happy life, my friend.
