Instrotech’s new range of LR-Cal vacuum and pressure hand-pumps are designed for easy calibration in the field of test pressure gauges, pressure transmitters and switches.
The units feature a volume adjuster enabling fine pressure control, and a bleeder valve.
The type 2911 is a heavy-duty calibration hand-pump for generating pressure of up to 7 bar. Model 2941 generates vacuum up to 900 mbar.
Pressure change sensitivity is 0,05 mbar making the calibration pumps highly suitable for the Hg, mmHg or m-bar ranges. Pressure connection is for tube 4/6 mm.
The hand-pumps are supplied with standard accessories of 300 mm tube, T-coupling, operating manual and an optional carrying case.
