The PV624 is a portable hybrid pressure controller base station that combines the advantages of manual pressure generation with fully automatic pressure generation and control. Using the PV624 with a DPI620G electrical calibrator and interchangeable PM620/PM620T pressure modules from the Genii advanced modular calibration system creates a uniquely capable, flexible, self-contained portable hybrid pressure controller.
  • In-the-field pressure range selection from the Genii PM620/PM620T pressure module family
  • In built barometer to enable accurate pseudo pressure measurements
  • Hybrid pressure generation and control from -0.9barg (-13psig) to 20barg (300psig)
  • Automatic selection of manual pressure generation, automatic pressure generation or pressure venting with large test volume capability
  • Fully automatic pressure generation and control to accurately maintain setpoint
  • Minimise in-the-field leaks with quick-fit pressure adapters
  • Physical or Bluetooth® wireless connection to a DPI620G electrical calibrator
  • In-the-field rechargeable battery pack replacement
