Clamp Ground Resistance Tester
Model: GRT-100
The GRT-100 is a new generation of landless pile test method of ground resistance meter. It adopted a new generation of black screen LCD backlit display and microprocessor technology, Ω+A synchronous display, convenient and quick measurement of ground resistance by way of induction, in measuring circuit grounding system, does not need to disconnect the ground down lead, does not need auxiliary electrodes, security quickly. It is widely used in telecommunication, electric power, meteorology, computer room, oil field, power distribution line, tower transmission line, gas station, factory grounding network, lightning rod and so on.
The Clamp Ground Resistance Tester GRT-100 is controlled by a microprocessor and can accurately measure the ground resistance, leakage current, and ground voltage. It uses fast filtering technology to minimize interference. 500 groups of test data can be stored at the same time, and the data can be monitored online by monitoring software, or uploaded to PC.
