High Precision Contact Resistance Tester 100A 200A 400A DC Micro-Ohmmeter for Circuit Breaker, Switchgear, Busbar and Electrical Contact Resistance Testing
Product Description The High Precision Contact Resistance Tester is a professional low-resistance measurement instrument designed to measure extremely low resistance values in electrical contacts and conductive connections. The tester uses a high-current DC test source to provide stable current through the device under test and accurately measures the voltage drop across the test point. The resistance value is then calculated and displayed in micro-ohms. It is widely used for
