Product Details

Product Features 

The HLY-III contact resistance tester features high output current, wide adjustment range, stable signal, compact structure, simple operation, intuitive reading, and can be used alone as a high-current source.

It uses a switching power supply output, with high precision, small size, and light weight.

It uses imported high-quality components, with strong anti-interference ability.

The HLY-III contact resistance tester is made using imported original high-stability constant voltage switching power supply, digital circuit and switching circuit technology. It is a special equipment for measuring contact resistance and loop resistance of switch control equipment, suitable for on-site high-voltage switch maintenance in power plants and power supply departments, and loop resistance testing in high-voltage switch factories.
