Additel ADT 912A Low Pressure 60 PSIG Calibration Test Pump

The Additel ADT 912A pneumatic pressure calibration test pump is a hand operated pressure pump designed to generate pressures from -14 psig (-0.95 bar) to 60 psig (+4 bar). A high-quality screw press is designed for fine pressure adjustment, with an adjustment resolution up to 0.01 Pa (0.0001 mbar/0.00004" Water). To reach the pressure as stable as possible during micro-pressure calibrations, an isothermal bellows chamber is designed for reducing the possible heat effects caused by environmental temperature change, and a specially designed shut-off valve make the pressure as stable as possible during calibration. A built-in gas-liquid isolator protects the pump from moisture and dirt to reducing the need for maintenance. Two hand-tight connectors installed on the pump allow easy connecting and disconnecting to the test pump without the need for thread tape or wrenches. The ADT912A is an ideal comparison test pump for low pressure applications on the bench or in the field.
