The DPC measures and generates pressure and can therefore be used as a pressure measurement device or as a test and calibration device for pressure sensors and pressure switches. An integrated lithium-ion battery makes the DPC the perfect companion for mobile calibration tasks. It is therefore no longer necessary to disassemble the systems for calibration, thus speeding up the calibration process and reducing associated costs to a minimum. Programmable pressure profiles enable the automation of individual calibration processes. By selecting between four measurement ranges, the calibrator can be perfectly adapted to the device being tested. In addition to offering maximum convenience, the DPC also has an extremely low measurement uncertainty and great long-term stability.
