Find Verified Clamp Ground Resistance Tester Suppliers, Manufacturers and Wholesalers

Application: ETCR2000 clamp ground resistance tester is a major technological breakthrough in traditional grounding resistance measurement. It is widely used in the grounding resistance measurement of electric power telecommunications meteorology oilfield construction and industrial and electrical equipment. When measuring circuit grounding system it is not necessary to disconnect the each connection wire and use auxiliary electrode it is safe and quick easy to use. Can measure the grounding fault which can not be measured by the traditional method because this instrument measure the integrated value of grounding resistance and ground lead resistance apply to the occasion that can not use the traditional method. Features: Apply to all kinds of ground lead.(round bar flat bar angle iron). Non-contact measured grounding resistance safe fast. Without using assistant ground rod. Without interrupting the grounding of the device under test. With double protecting insulation. With strong anti-interference ability and high accuracy. Use 5# alkaline batteries convenient for users.

Product description Earth ground resistance tester is a high-precision testing instrument used in various fields such as substations to test grounding resistance and related parameters.The instrument is of an integrated structure, with a built-in frequency conversion power supply module, and the output power supply is continuously variable in frequency. The frequency can be changed to 45Hz or 55Hz, the high-speed processor core is built in, and the high-end digital filtering technology is adopted, thus effectively avoiding the interference of power frequency electric field to the test and fundamentally solving the difficult problem of accurate measurement under strong electric field interference.
