Features
1. Earth resistance tester, in the measurement of a grounding system with loop current, does not require breaking down the grounding wire, and no need auxiliary electrode.
2. With large LCD display screen, clear data, easy to read. Can test ground resistance and loop resistance test. It is safe, fast and simple in use.
3. Widely used in the grounding resistance measurement of the power, telecommunications, meteorology, oilfield, construction and the industrial and electrical equipment.
4. Increase sound and light alarm function, with "beepbeep beep" alarm sound and increase the interference signal recognition indicator function, with "beepbeepbeep" indicator.
5. Earth resistance tester can measure the integrated value of the grounding body resistance and the grounding lead resistance.
