MVT 200B series contact resistance meters are a new generation of highly portable, lightweight and easy-to-use products for measuring the resistances of various test objects like Circuit Breakers, Isolators, Disconnectors, Bus-Bars, Joints, etc. They inject current up to 200 A through the device under test and measure the micro-ohm resistances accurately, even in noisy switchyard conditions. Thus, MVT is an ideal preventive maintenance tool for measuring critical resistances.
