ZKD Circuit Breaker Vacuum Bottle Vacuum Degree Tester uses the new excitation coil magnetron discharge method to test the vacuum of the arc extinguishing chamber without disassembling the arc extinguishing chamber.
ZKD also used computer for synchronous control, data acquisition and processing, and the sensitivity of ZKD vacuum degree tester in the field test of the vacuum interrupter arc chamber is 10-5Pa.
The most outstanding feature of this instrument is the use of new excitation coils and data processing methods to achieve the non-demolition measurement of vacuum.
