• Rugged portable design built for demanding field environments

The Megger MJÖLNER 600 Micro-Ohmmeter gives technicians the power to measure extremely low resistance values with confidence. It delivers test currents up to 600 A, allowing accurate testing of circuit breaker contacts, busbar joints, and other high-current connections. The instrument incorporates DualGround™ safety technology, which allows both sides of the breaker to remain grounded during testing. This approach helps improve safety while working in substation environments. The bright colour display presents measurements clearly and keeps test setup straightforward. Automatic test sequences speed up repetitive testing and help maintain consistent results. Built with a robust portable design, the MJÖLNER 600 performs reliably during commissioning, maintenance, and detailed substation inspections.
