DH Instruments PPC4 precision pressure calibrator

The DH Instruments division of Fluke Corporation has an enhancement to its PPC4 precision pressure controller/calibrator product line. PPC4 is a high-performance pressure calibrator for testing pneumatic pressure instruments. It is designed to provide versatility and ease of use in calibration labs and manufacturing environments.

The dynamic control has been improved, extending the minimum controlled pressure down to 1 kPa. The maximum pressure range of the PPC4 has now increased to cover the absolute pressure range of 1 kPa (0.15 psi) to 14 MPa (2000 psi) and gauge pressure equivalent, including very low differential pressures.

PPC4 allows users to select the user interface that best fits their application and budget. Bench top users can select the advanced graphic colour display with point-and-click navigation to streamline pressure calibration and testing tasks. The graphical user interface now supports 11 different languages, including Chinese, Czech, English, French, German, Italian, Japanese, Portuguese, Russian and Spanish.

The calibrator includes a front panel USB connection and free cockpit software for full PC-based plug-and-play functionality.

It uses DHI’s individually characterised, quartz reference pressure transducer (Q-RPT) modules for increased precision and reduced measurement uncertainty and DHI’s Compass for pressure calibration assistance software provides an advanced off-the-shelf tool to automate calibration and testing processes quickly and handle a wide array of special requirements. The AutoRange feature supports infinite ranging, automatically optimising all aspects of operation for the exact range of the device being calibrated.
