10A MicroOhm Meter MI 3250 – Metrel

Metrel’s 10A MicroOhm Meter is a portable low resistance ohmmeter for measuring low resistances of breakers and switches, busbars, cable joints, small to medium sized transformer and motor windings for industrial application, etc., with test current up to 10A. The used 4-lead Kelvin testing method together with automatic bidirectional procedure ensure very high accuracy of test results (0.25%). This 10A MicroOhm Meter can be powered by mains or internal rechargeable batteries. Test results can be stored on the instrument and with PC software HVLink PRO that is supplied as a part of standard set enables transfer of measured results to PC where they can be analysed or printed.
