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
• Autonomous calibration wizard to store procedures and calibration data
