PV624 portable hybrid pressure regulator

The PV624 is a portable base station for hybrid pressure controllers that combines the benefits of manual pressure generation with fully automatic pressure generation and control. Using the PV624 with a DPI620G electric calibrator and interchangeable PM620/PM620T pressure modules of the Genii advanced modular calibration system creates a uniquely multifunctional, flexible, self-contained portable pressure calibrator.

Application

With this rugged pressure regulator,
pressure set points can be easily and quickly
adjusted and kept stable. The instrument
also supports large test volumes and has a
long battery life.

This new base station is part of the Genii
Advance modular calibration system, which
allows you to create a multifunctional
portable pressure controller. Combine the
PV624 with any DPI620G electric calibrator
and a PM620 pressure module for a
complete solution.
