Digital low resistance micro-ohmmeters, known as DLRO, measure the contact resistance of a variety of facility electrical systems, like switch and circuit breakers, aircraft frame bonds, rail and pipeline bonds, and more.  Using accurate, reliable test equipment is essential when testing at such low resistance. Elektrorent carries DLRO and contact resistance ohmmeters from reputable, trustworthy brands like AEMC, Biddle, Megger and more.
