Introduction:
Clamp ground resistance tester, also known as loop resistance tester, is used to test grounding resistance.
The instrument uses a new black luxury screen design, resistance and current display in the same screen, and also has a real-time clock, data storage, data access, alarm, automatic shutdown and other functions.
The machine is beautiful and upscale, has a wide range, high resolution, convenient operation, easy to carry, accurate, reliable, stable performance, strong anti-interference ability.
Moreover, it has a shockproof, dust-proof, moisture-proof structure and is a commonly used 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 various grounding resistances such as telecommunications, electricity, meteorology, computer rooms, oil fields, power distribution lines, transmission lines of iron towers, gas stations, factory grounding networks, and lightning rods.
The clamp ground resistance tester is controlled by the microprocessor and can accurately detect the ground resistance. It uses a fast filtering technique to minimize interference. At the same time data storage and data upload functions
