Ground resistance test system has the characteristics of small volume, light weight, convenient carrying, strong anti-interference performance, high accuracy, etc. A large number of on-site tests and users' use show that when grounding grid tests are carried out in the harsh electromagnetic environment of the substation, the measurement data of the grounding resistance tester of the grounding grid are accurate, stable and good in repeatability, and are ideal instruments for measuring the characteristic parameters of large and medium-sized grounding grids.

1. Accurate and fast, the instrument uses a professional DSP fast digital signal processor as the processing core, which greatly improves the operation and processing capability of the instrument itself on the premise of ensuring accurate measurement data.
2. The instrument is internally equipped with a calendar chip and a large-capacity memory, which can store the test results in chronological order, check the historical records at any time and print them out.
3. The data measured by the instrument can be exported through U disk, and then related data can be consulted and managed on pc.More details: Ground Resistance Test SystemOn Social:/in/gdmk
