Megger DLRO600 – Micro-Ohmmeter

• Delivers test currents up to 600 A for high-precision low-resistance testing
• Measures resistance from 0.1 µΩ to 1 Ω with excellent accuracy
• Uses automatic current reversal to minimise thermal EMF errors
• Features a large colour display for clear measurement results
• Provides internal data storage and USB download capability
• Rugged portable design suited to substation and industrial environments

The Megger DLRO600 Micro-Ohmmeter is designed for demanding low-resistance testing where high current and reliable results matter most. It delivers powerful test currents up to 600 A, allowing technicians to measure very low resistance values across busbar joints, switchgear contacts, and critical conductors with confidence. Automatic current reversal actively reduces errors caused by thermal EMFs, improving measurement accuracy during testing. The instrument displays results clearly on a bright colour screen, making readings easy to review in both indoor and outdoor environments. Internal memory allows users to store measurements and transfer them later for documentation or analysis. With its robust construction and portable design, the DLRO600 supports accurate connection testing during commissioning, preventative maintenance, and detailed system inspections.
