AEMC 6255 Micro-Ohmmeter

Overview

The AEMC 6255 Micro-Ohmmeter is a specialized low-resistance tester using a four-lead Kelvin measurement method for exceptional accuracy of 0.05%. Designed for both plant maintenance and field service, it measures from 1µΩ to 2500Ω with selectable test currents from 1mA to 10A. The instrument supports continuous operation up to 60 minutes at 10 amps and stores up to 1500 measurements.
