Megger DLRO200 Digital Low Resistance Ohmmeter

Overview

The Megger DLRO200 is a 200 A digital low resistance ohmmeter designed for measuring resistances between 0.1 µΩ and 1 Ω using high test currents. The four-terminal measurement technique cancels the resistance of test leads from the measurement, ensuring accuracy. Compact and lightweight at less than 15 kg, the DLRO200 is suitable for workshop, production floor, or field applications where high-current testing is required, such as circuit breaker contacts, switch contacts, and busbar joints.
