Additel ADT 914A Pneumatic 375 PSIG Pressure Calibration Test Pump

The Additel ADT 914A pneumatic pressure calibration test pump is a hand operated pressure pump designed to generate pressures from -14 psi (-0.95 bar) to 375 psi (+25 bar). A high-quality screw press is designed for fine pressure adjustment, with an adjustment resolution up to 10 Pa (0.1 mbar). 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 ADT914 is an ideal comparison test pump for pressure instruments calibration.
