Megger MJOLNER 200 Micro-Ohmmeter - Choice of Cable Set
The Megger MJOLNER200 is a high accuracy low resistance ohmmeter, made for testing the resistance levels of circuit breaker contacts, bus-bar joints, contact elements in bus-bars and other high current links.
Built inside its own suitcase for easy transportation, the MJOLNER200 is powered by a built-in microprocessor system to ensure fast response, easy access to all of the procedures you need and even gives you the ability to carry out fully automatic testing.
Megger's MJOLNER200 is designed for low current applications up to 200A DC; this is best suited when testing high current devices such as circuit breakers, ensuring your test results are as accurate as possible.
For added safety, the MJOLNER200 is equipped with Megger's DualGround. This grounds both sides of the unit, ensuring a safe, fast and easy workflow and giving you the peace of mind to know you're working safely even in demanding conditions.
The MJOLNER200 is equipped with an interface for connection to PC and even has a built-in printer as standard for on-the-go reporting.
