Vacuum Breaker Tester

The HM6070 Vacuum Switch Vacuum Tester employs a new type of excitation coil and utilizes the magnetron discharge method to test the vacuum level of the arc-extinguishing chamber without the need to disassemble it. Additionally, the device uses a microcomputer for synchronous control and data acquisition and processing, enabling on-site testing of the arc-extinguishing chamber's vacuum level with a sensitivity of 10⁻⁵ Pa.
