DMO200 Digital Micro-Ohmmeter
200 A DC micro-ohmmeter for contact-resistance testing on breakers, isolators and busbar joints, resolving to 0.1 µΩ at 6.9 kg.
Measures contact and joint resistance down to 0.1 µΩ using test currents from 1 A to 200 A DC, with ripple held under 2.5% so readings stay stable on inductive joints.
Range selection is automatic and current, voltage and resistance are displayed together, so a technician reads the full picture on one screen rather than deriving resistance by hand. Readings persist on the display after the output is switched off.
