Megger MOM2 Handheld 200A Micro-Ohmmeter

Megger MOM2 Handheld 200A Micro-Ohmmeter

The MOM2 handheld 200 A micro-ohmmeter has been designed to measure the resistance of circuit breaker contacts, busbar joints, and other high current links. To do this effectively, it uses an ultra capacitor to generate its high output current. This ultra capacitor is able to store a huge amount of energy compared to conventional capacitors and can deliver a very high current during discharge thanks to its very low internal resistance.

This micro-ohmmeter can be used anywhere to measure a low resistance value with high accuracy. What's more, with the MOM2, it is possible to make measurements according to the DualGround method, meaning that the test object will be grounded on both sides throughout the test providing you with a safer, faster, and easier testing experience.


The ruggedness and lightweight makes MOM2 a handheld instrument very suitable for field work, such as in substations. The unit comes with a strong rubber holster accessory which makes it extra durable. MOM2 is dimensioned to make a full day’s work of testing without recharge. It can store 180 test values and transfer test data to a PC via Bluetooth.

MOM2 uses an ultra capacitor to generate the high output current. The ultra capacitor is able to store a huge amount of energy compared to conventional capacitors and can deliver very high current during the discharge thanks to its very low internal resistance.

While testing, the capacitor is discharged through the test object and the voltage drop across- and the current flow through the test object are continuously and synchronously sampled. The resistances calculated from the individual samples are then averaged to obtain the final value.
