The calibration handpumps 2911 and 2941 have been designed for easy to use pressure calibration equipment „in the field“, for testing pressure
gauges, presure transmitters, pressure switches etc.
With volume adjuster, enabling fine pressure control, and bleeder valve. Thanks to their sensitivity, the calibration handpumps 2911 and 2941 are very suitable for “in Hg”, “mm Hg” or “mbar”-ranges.
