Product Introduction:

   The switch mechanical characteristic tester is a computer intelligent testing instrument developed for high-voltage vacuum switches. This instrument uses the most advanced microelectronic technology to quickly provide accurate and reliable measurement data, displays all data of close (open) operations in Chinese, and stores all data you need. It provides Chinese prompts for possible switch faults and incorrect connection of external signal lines. The instrument is simple and intuitive to operate, and the measured data can be stored, reviewed, and printed in Chinese.
