Product introduction:

 

 

 

Ybl-iii zinc oxide arrester tester is a special test instrument used for field and laboratory testing various electrical parameters of arresters. This instrument takes the advanced microcomputer as the control and the computation core, USES the accurate mathematics model, has considered the outside world to the instrument measurement interference fully, the software itself measurement is accurate and reliable. The instrument is completely isolated from the lightning arrester, which ensures the safety of the instrument and the user. The instrument adopts large-screen liquid crystal display, which can provide sufficient text prompt and make man-machine dialogue more convenient. At the same time, it provides field wiring display. The backlight function of the instrument makes it still clear in the outdoor display and easier to use.
