Perform reliable low resistance measurements using test currents from 10 to 200A and resolution to 1µO. The four-wire Kelvin bridge method eliminates test lead resistance to provide measurement accuracy up to 0.25%.


AEMC® provides versatile, rugged micro-ohmmeters suitable for lab and field use with available test currents from 10 to 200A. Utilizing a four-lead Kelvin method of testing, they accurately measure very low resistances in the micro-ohm range within 0.25%. Other features include data storage and report generation, automatic temperature compensation (model dependent), and polarity reversal. Robust circuitry design allows higher current testing for long periods in time.
