The PV624 is a portable hybrid pressure controller 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. The PV624 hybrid pressure controller offers an easy and fast method to accurately maintain pressure set points. Hybrid pressure control also supports large test volumes and long battery life. With a robust design and tool-less pressure connection, the PV624 is ideally suited to perform pressure testing and calibrations in the field.
