Ground Network Earth Resistance Tester

Type: ZC-413
    This device applies to test frequency ground resistance, contact voltage, pace voltage and earth electric resistivity. It adopts different frequency anti-jamming technique, can get the data under 50Hz in strong interference circumstance. The maximum measured current is 5A , which will not cause the electric potential of the grounding device too high, it with strong anti-interference ability at the mean time, so it does not need power off during the test.
