High-Accuracy Micro-Ohmmeter for Ohmic and Inductive Loads

PROMET L100 is a compact, high-precision measuring device for determining resistance values in the μΩ range. The output is independent of the mains input.


The use of four-wire measuring technology and high test currents of up to 100 A enable PROMET L100 to meet the most stringent accuracy requirements. In addition PROMET L100 can also be used to determine the winding resistances of transformers, motors and instrument transformers.
