      • The JHMD-HQ series includes JHMD-HQ1 (SF6/N2), JHMD-HQ2 (SF6/CF4) and JHMD-HQ3 (SF6/N2, SF6/CF4) models
      • The instrument adopts electronic pressure adjustment, the user 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 to the equivalent pressure of the gas mixture at 20 ° C
