Product Introduction:
CHR-303 high-voltage switch dynamic characteristics tester is a special instrument we developed to adapt to the need of site testing for high-voltage switch performance characteristic. It is based on SCM to take sample, process and output. Its main feature is adopting prompts of man-machine dialogue mode operation, displaying results and printing out. It has advantages of intellectualization, multi-function, accurate data, strong anti-interference, simple operating, small size, light weight, beautiful appearance etc. It is applicable to a variety of indoor, outdoor dynamic characteristics tests for less oil, more oil switch, vacuum switch, sulfur hexafluoride switch.
