Product Overview: Mensor CPH7650 Wally Box IV Portable Pressure Calibrator – DISCONTINUED


Wally Box IV Portable Pressure Calibrator


The portable pressure calibrator model CPH7650 is a compact, portable pressure calibrator, which has been designed for mobile use as well as for stationary workshop and laboratory testing. An integrated electrical pump enables you to generate pressures up to 20 bar (300 psi) and an integrated electrical module also enables you to supply transmitters or sensors with a current of max. 30 mA (voltage (idling) = DC 24 V), in addition to the traditional measurement of current and voltage signals.


  • Calibration service companies and service industry
  • Measurement and control laboratories
  • Quality assurance

Special features

  • Measurement and electrical pressure generation at the touch of a button with integrated pump, from -0.85 … +20 bar (-12 … 290 psi)
  • Accuracy: 0.025 % FS (incl. calibration certificate)
  • Generation/measurement of 4 … 20 mA, and DC 24 V voltage supply to power transmitters
  • Robust case design, IP67


With the portable pressure calibrator, not only are accurate pressure measurements possible, but also exact current and voltage measurements, as well as a DC 24 V voltage supply for test items are enabled. Pressure values and electrical measured values are simultaneously shown in the display. The calibrator is integrated into a robust, as well as dust and waterproof transport case. Thus the mobile pressure calibrator is particularly suited to use in harsh industrial environments.
With the built-in NiMH rechargeable battery, a battery life of approximately 50 hours or 125 pump cycles up to 20 bar (290 psi) is guaranteed. The external universal power supply is designed for an operating voltage of AC 100 … 240 V.


The exchangeable model CPT6000 reference sensor offers an accuracy of 0.025 % of span. The temperature compensation of the built-in sensor safeguards the accuracy for applications in the field. Readings can be displayed in one of 13 standard units.
