DLRO / Contact Resistance Ohmmeters

Digital micro-ohmmeters and DLROs measure contact resistance of switch and circuit breakers, aircraft frame bonds, and rail and pipeline bonds just to name a few of the applications. Test currents range from 0.5 mA to 100 amps offering precise low-resistance measurement applications. Our inventory of DLRO rentals include a wide variety of current ranges and resolution, covering the following applications: switch and circuit breaker contacts, transformers and generators, motor windings, busbar and other joints, aircraft, rail and pipe bonds, cable splices, welds and fuses, metal alloys, graphite electrodes and other composites, wire and cable resistance measurements.
