DER2571 Digital Grounding Resistance Tester

DER2571 Digital Grounding Resistance Tester

This product is applicable to the measurement of grounding resistance and grounding voltage for various grounding devices, and also measurement of the resistance value soil resistivity and low resistance conductor.

With synchronous detection and other advanced technologies, strong anti-interference capability.

LCD digital display, high resolution, accurate value indication.

Battery gives power supply, with a voltage indicator.

When the tested grounding polarity or the current polarity auxiliary grounding resistance is over the upper limit value, there will be "OPEN CIRCUIT" displaying in the lower left corner.

Convenient operation, convenient portability, low power consumption.

Its structure is shockproof, dustproof, waterproof, and it can be used in bad working environment.
