Digital ohmmeter MH series

portablelow-resistance

The digital micro-ohmmeter MH-100u is a microprocessor-controlled portable instrument designed to measure very low resistances with high accuracy with test currents from 1 mA to 100 A. The MH-100u micro-ohmmeter operates according to the 4 arms method (Kelvin bridge), thus avoiding the effect of the resistance of the injection cables. The test current can be selected by the operator and the indication is obtained by comparison with highly stable internal standards. The result is shown on an easy-to-read alphanumeric display. It also has a USB output to extract the data to media to manage measurements. Control of switchgear in MV Centres or Substations and electrical installations. Contact of circuit breakers, bus bars, windings of transformers and motors.
