1. The ground resistance tester, in measuring a grounding with loop current, does not require breaking the ground wire and does not need auxiliary electrode.
2. With large LCD display, clear data and easy to read. It can test the ground resistance and loop strength test. It is safe, quick and easy to use.
3. Widely used in the measurement of the ground resistance of energy, telecommunications, meteorology, oilfields, construction and industrial and electrical equipment.
4. Increase the sound and light alarm function, with beep-beep alarm sound and increase the function of the interference signal recognition indicator, with bip-bep-beep indicator.
5. The ground resistance tester can measure the integrated value of the ground body resistance and the resistance of the grounding wire.
