JHMD-30 SF6 density relay calibrator
Using electronic pressure adjustment, the calibrator has a pre-pressurization function, simulating the SF6 gas density relay touchpoint does not move for a long time, and the first step-down automatically completes the calibration
Realize the first touchpoint operation pressure value and contact resistance value test of density relay, and automatically complete the statistical analysis of set point deviation and switching difference
