The MJÖLNER200 is a 200 A micro-ohmmeter with DualGround safety features. It has been designed to measure the resistance of circuit breaker contacts, bus-bar joints, contact elements in busbars, and other high-current links with safety, ease of use, and versatility in mind. Indeed, it's high current capability goes up to 200 A DC (a true DC ripple-free current), so you avoid will problems with incorrect test results due to low test current when testing high current devices such as circuit breakers. As such, this micro-ohmmeter can be used anywhere to measure a low resistance value with high accuracy.
The MJÖLNER200 also has the ability to make measurements according to the DualGround™ method. This means that the test object will be grounded on both sides throughout the test, giving you a safer, faster, and easier testing process. Additionally, its lightweight yet rugged case design makes the MJÖLNER200 an excellent choice when you need a portable solution in the field. When the case is closed, the product can withstand the impact of water, dust, or sand – it even floats!
