Introduction:

• GDGK-303 Mechanical Properties of High Voltage Circuit Breaker Tester is designed to meet the need of testing high_voltage switches .     

• GDGK-303 Mechanical Properties of High Voltage Circuit Breaker Tester takes the micro controller unit(MCU) for core to sample, process and then output; the main characteristic is that it's operated in Chinese, for example ,the results are displayed and printed in Chinese. 

• GDGK-303 Mechanical Properties of High Voltage Circuit Breaker Tester has many advantages such as intelligence, multi-function, accurate data, strong anti-jamming, easy operation, small size, beautiful appearance, etc.

• GDGK-303 Mechanical Properties of High Voltage Circuit Breaker Tester can test the switches as follows:indoors or outdoors switches with less oil or more oil,vacuum switches, SF6 switches and so on.
