Product overview Fully automatic testing with microprocessor control Safe testing with DualGround™ and remote control Remote operation via mobile app True DC – pulse-free Lightweight case – resistant to water, dust, and sand PC interface connectivity MJÖLNER200 is a 200 A micro-ohmmeter with DualGround safety features. It is designed for measuring contact resistance of circuit breakers, busbar connections, contact elements in busbars, and other high-current connections, emphasizing safety, ease of use, and versatility. Its high current capability reaches 200 A DC (true DC without pulses), preventing measurement errors caused by low test current when testing high-current devices such as circuit breakers. This micro-ohmmeter can be used anywhere for precise low-resistance measurements.
MJÖLNER200 also supports the DualGround™ measurement method, meaning the test object is grounded on both sides throughout testing, providing a safer, faster, and simpler testing process. Its lightweight yet durable case makes MJÖLNER200 an excellent choice for portable field solutions. The enclosed housing is resistant to water, dust, and sand – it even floats!
