KDHL-200A circuit resistance tester is also known as circuit breaker conductive circuit. It is used to detect the electrical conductivity, which plays an important role in ensuring the safe operation of the switch. The conductive performance can be reflected by the size of the conductive circuit resistance.

Measurement function: fast measurement, 10S measurement, 60S measurement.
The instrument has the characteristics of small volume, light weight, strong anti-interference ability, high precision, easy operation, perfect protection function and so on.
The use of newer power technology, can be a long time continuous output of large current, multi-current gear output.
Using the precision instrument operational amplifier and high precision quadruple integration A/D converter, combined with high performance 16 bit single chip microcomputer, the system automatically switches the magnification according to the signal size, which ensures the test accuracy of the product.
The test current comes from the high-precision 100A switching constant current power supply, and the test is fast and accurate without manual adjustment.
