HT3020 Clamp Ground Resistance Tester is a new generation of groundless pile measurement method that our company's technical team meticulously developed. It uses a brand new generation of LCD, black screen backlight display and microprocessor technology to measure the grounding resistance through inductive method. When measuring a grounded system with a loop, it is not necessary to disconnect the ground lead wire, and no need for auxiliary electrodes. It is safe and fast. Widely used in telecommunications, electricity, meteorology, computer rooms, oil fields, power distribution lines, iron tower transmission lines, gas stations, factory grounding networks, lightning rods and so on. The instrument has the test precision, fast, simple , stable , reliable and other features HT3020 Clamp Ground Resistance Tester is microprocessor controlled and accurately detects ground resistance. It uses a fast filtering technique to minimize interference. At the same time store 500 groups of data, with unique features such as numerical maintenance and intelligent alarm prompts
