Knowledge and information

This case offers improved efficiency to quickly and safely perform clean, high pressure calibrations at your own location.

  • Supports pressure ranges with full scale from 20 MPa down to 0.7 MPa in a single system

  • Simple, compact and easy to operate

  • Built-in refillable 28 MPa storage tanks for pressure supply

  • Precise test pressure control using a pressure balanced volume controller

  • Protected against overpressure

  • Three analogue pressure gauges for monitoring pressure in storage system, regulated supply

pressure and pressure at test ports

  • Two test ports

  • 316 SS high pressure tubing and fittings

Self contained unit provides pneumatic pressure for calibration and testing up to 250 bar using a Beamex MC6 multifunction calibrator with pressure module.

The unit is designed as an additional tool for your Beamex MC6 multifunction calibrator allowing fast and safe generation of high pneumatic pressure up to max 25 MPa.

• Also version available for Beamex MC5 


The built-in high pressure gas storage system is filled through the appropriate connection. Three separate monitor gauges are mounted to indicate storage system pressure, regulated pressure and pressure at test ports. The maximum test pressure is set using the supply regulator. The test pressure at the two test connections is precisely controlled by two fine metering needle valves and the pressure balanced volume adjuster.

The installed Beamex MC5/6 multifunction calibrator displays the test pressure. Externally generated pressures can also be measured via the test connections. The instrument is supplied with quick-connect test and filling hose, a 1⁄4" NPT male adaptor for the test connection and filling and a refill connector.
