This compact, portable and easy-to-use micro-ohmmeter is perfectly suited for checking and measuring contact resistance in high voltage circuit breakers, disconnecting swtiches (isolators) and busbar joints.

The MOM200A can output current from 0-200A and has resistance measurement range from 0 to 1999μΩ and 0 to 19.99mΩ. With the MOM200A, you'll be able to find poor connections with its ability to output 100A for extended periods, or use its extended range of up to 20 milliohms to measure a wide variety of different connections.

Megger's MOM2 is designed with portability in mind; it comes as standard built inside its own carrying case!
