JH1006A 100A Electrical Instrument Contact Loop Resistance Tester Micro Ohm Meter Switch Circuit Breaker Tester Loop Tester

Product Overview:

The JH1006A Contact Loop Resistance Tester has operation panel of this instrument adopts an ergonomic design that conforms to operating habits. It adopts high-frequency switching power supply and digital circuit technology, and is suitable for measuring the circuit resistance of switch control equipment. The testing current adopts the DC 200A recommended by the national standard. The circuit resistance can be directly measured under DC 200A, and the test results are displayed on a large LCD TFT color screen, with functions such as data storage, output printing, and time setting. There are 50A, 100A, 150A, and 200A gears for users to choose from; Customized testing time, with a maximum set time of 60S, it is a very stable contact resistance tester with performance exceeding that of imported high current micro ohmmeters. Comply with on-site high-voltage switch maintenance by power and power supply departments and high-voltage switch factory circuit resistance.
