Contact Resistance Meter

The contact resistance test measures the resistance of electrical contacts of circuit breaker ,isolators& bus bar. It measures the resistance at the micro- or milli-ohm level and is used primarily to verify that electrical connections are proper. It helps to detect loose connections ,eroded contact surfaces, contaminated or corroded contacts. It is important for contacts that carry large amounts of current as higher contact resistance leads to higher losses I2R and lower current carrying capacity.
