The Megger Programma MOM200A Micro-Ohmmeter helps you check low resistance joints in breakers, isolators and busbars with confidence. It drives high test current and gives clear, steady readings, so faults show before they cause heat and loss.
Performance and range
You set the output to suit the joint and the task, then watch stable results track small changes. The instrument covers very low micro-ohm values and extends into the milliohm range, so one unit fits many links and joints.
Built for field work
The unit is portable and sits in a tough case that protects it between jobs. The interface stays simple, so setup and testing take little time even in busy substations and industrial plants. You can choose 115 V or 230 V versions and kits with leads and a transport case, so the right bundle matches site power and travel needs.
A long, steady output helps you find weak connections that warm under load and waste power. The design supports planned maintenance by proving the quality of joints across switchgear, busbars and line links before they fail.
