PPC4 Pressure Controller / Calibrator

Choose your interface, transducers and more for maximum versatility. The PPC4, DHI’s fifth generation pressure controller/calibrator, continues to break new ground with an unprecedented combination of high end performance, operational versatility and long term reliability.


Now you can choose your local user interface to best fit your application and budget. If you are a bench top user, the new graphic color display with point-and-click navigation will streamline your pressure calibration and testing tasks. Or, if PPC4 spends most of its time interfaced with a computer, choose the basic front panel. Both the basic PPC4 and PPC4-ui with advanced local user interface include standard remote interfaces and a front panel USB connection with free “cockpit” software for instant PC plug-and-play functionality.

PPC4 includes individually characterized, quartz reference pressure transducer (Q-RPT) modules to precisely measure and control pressure. DHI’s Q-RPTs come with a choice of three performance and cost levels, from the unparalleled precision of Premium class to the new, economical Full Scale Standard class.

The AutoRange™ feature supports infinite ranging, quickly and simply optimizing speed, measurement uncertainty, control limits and safety features for the exact range specified by the user.
