DVM-99 Vacuum Switch Vacuum Degree TesterWith the rise of the oil-free wave in medium-voltage switches, vacuum switches have been widely promoted and applied due to their unique advantages.Due to production processes and on-site usage environments, some vacuum switches may experience varying degrees of leakage in their vacuum arc extinguishing chambers during operation, and some may leak to the point where they cannot interrupt normally within their normal lifespan.
1. Can quantitatively measure the vacuum degree inside the arc extinguishing chambers of various types of vacuum switches.
2. No need to disassemble the vacuum switch during on-site measurement.
3. Test results are accurate and reliable.
4. LCD with Chinese character display, making operation simpler and more convenient.
5. Can save, print, and view test data.
6. The instrument comes with an RS232 communication interface, which can connect to a computer to achieve functions such as downloading vacuum degree-ion current curves and estimating lifespan.
7. The instrument is lightweight and easy to carry.
