Micro-Ohm Meter

A micro ohm meter, also known as a digital low resistance ohmmeter (DLRO), measures low resistance values in micro-ohms at specified currents. Precision ohmmeters that use the four-wire, Kelvin probe system can eliminate contact resistance and reduce errors caused by lead resistance. Instruments for low resistance measurement are key to field and laboratory applications requiring high accuracy. The instruments can measure bonding joints, circuit breakers and contact or fuse resistance.
