•   Specifically designed for measuring contact resistances in circuit breakers, disconnecting switches, bus-bar joints, and other such devices
•   Safer testing using the patented DualGround™ technology to test circuit breakers with both sides grounded
•   Fully automatic testing- microprocessor controlled
•   Wide measuring range and test currents
•   High-Power and lightweight

The MJÖLNER Series is designed to measure the resistance of circuit breaker contacts, bus-bar joints, contact elements in bus-bars and other high-current links. This product has been designed with safety, ease of use and versatility in mind. It can be used anywhere to measure a low resistance value with high accuracy. It conducts true DC ripple free current testing of bus bars, circuit breakers, fuses, etc.
