Contact Resistance Meter From SB Electrotech

A Contact Resistance Meter is a specialized electrical testing instrument used to measure very low resistance values in electrical contacts, joints, switches, circuit breakers, and busbars. It evaluates the quality and efficiency of electrical connections by detecting loose, corroded, or damaged contacts that may cause overheating, power loss, or equipment failure. The device measures resistance in micro-ohms or milli-ohms by passing a constant current through the connection and monitoring voltage drop. It is widely used in electrical maintenance, testing, and industrial applications for ensuring safe and reliable system performance.
