Chauvin Arnoux CA 6471 Earth Tester, 99.9kΩ CAT IV 50 V

The Chauvin Arnoux C.A 6471 earth and resistivity tester can also be used to measure the resistances of the auxiliary rods RS and RH, as well as any disturbance voltages. And its suitable for all types of measurement environments, even the most difficult, this method guarantees measurement of auxiliary-rod resistances up to 100 kΩ and disturbance voltages of 60 Vpeak.

Possibility of selecting the measurement frequency
Automatic calculation of resistivity and coupling
Multi-function testers
Excellent accuracy and resolution
