HT ITALIA – M71

M71 has been developed to measure earth resistance with 2 wires and 3 wires by voltammetric method in compliance with standard IEC/EN61557-1.

Compact earth resistance tester

M71 has been developed to measure earth resistance with 2 wires and 3 wires by voltammetric method in compliance with standard IEC/EN61557-1.

This device allows carrying out measurements with a wide measuring range (50kO) and an efficient internal automatic compensation of the disturbance effects found on the installations, and it is provided with an ergonomic design with electronic function selector for quickly carrying out the tests. The 2-wire method allows carrying out earth measurement by taking advantage of appropriate external masses as a reference (metal surfaces, tubes, neutral conductor, etc.), which is particularly useful in private environments where, because of logistic problems, it is not possible to use the 3-wire method.
