The KDZK-A Vacuum Degree Tester is a professional instrument for evaluating the vacuum state of vacuum interrupters, based on the magnetron discharge principle. It uses a single-chip microcomputer as the core control unit, adopting ion charge calibration to effectively suppress interference from intermediate-state power supplies. It enables non-destructive testing without disassembling the interrupter, directly displaying the vacuum value to help users grasp the vacuum status accurately. With high precision, strong anti-interference capability, and a portable design, it is an essential device for on-site maintenance, installation, and production testing of vacuum circuit breakers.
