Megger MOM2 Micro-ohmmeter, MOM200A 230 V with access., 10m BD-12391

Up to 220 A „ Battery supplied „ Lightweight – 1 kg „ Safe test – DualGround™ „ Auto range: 1 μΩ to 1000 mΩ „ Bluetooth® PC communication „ Complies with IEEE and IEC standards The MOM2 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 micro-ohmmeter can be used anywhere to measure a low resistance value with high accuracy. 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. 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.
