SF6 Density Calibration Series

JHMD-HQ series SF6 mixed gas density relay calibrator
  • JHMD-HQ series SF6 mixed gas density relay calibrator

JHMD-HQ series SF6 mixed gas density relay calibrator

 
recommendation index：
Percentage of SF6 mixture can be input arbitrarily
Automatic identification of failures during testing
Automatically store, review, and print test data
High degree of intelligence, safe and reliable
  • 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
