The NEW, revolutionary, MOM2 Micro-ohmmeter is designed to measure the resistance of circuit breaker contacts, bus-bar joints and other high-current links. This product is designed with safety, ease of use and versatility in mind.

The 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. The microhmmeter can be used anywhere to measure a low resistance value with high accuracy.

With MOM2 it is possible to make measurements according to the DualGround™ method. This means that the test object will be grounded on both sides throughout the test giving a safer, faster and easier workflow

 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.

The microhmmeter can be used anywhere to measure a low resistance value with high accuracy. With MOM2 it is possible to make measurements according to the DualGround™ method. This means that the test object will be grounded on both sides throughout the test giving a safer, faster and easier workflow. This gives a personal safe, quick and easy measurement.

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 190 test values and transfer test data to a PC via Bluetooth.

Low weight, ease of use and versatility has been key issues during product development. New patent pending technology has made MOM2 small and light, it weighs about 1 kg. Despite the small size and light weight the instrument can deliver a maximum current of about 220 A short duration and up to 100 A for three seconds.
