China Megger DLRO600 600 A micro-ohmmeter Suppliers, Exporters

The Megger DLRO600 is a 600 A micro-ohmmeter capable of measuring resistances between 0.1 Î¼Î© and 1 Î© at high currents. This versatile instrument can source DC test currents from 10 A to 600 A, depending on the load resistance and supply voltage, and uses a four-terminal measurement technique to remove the effects of test lead resistance from the measurement.
