JHMD-HQ series SF6 mixed gas density relay calibrator
Using electronic pressure adjustment, users can input the volume ratio of SF6 mixed gas at will, and automatically complete the pressure and contact resistance test of the mixed gas density relay
Automatically converts the current temperature and pressure into the equivalent pressure of the mixed gas at 20 ° C. It is an intelligent and environmentally friendly calibrator
