The Additel ADT 914 -14 psi to 375 psi Handheld Pneumatic Pressure Test Pump is a hand operated pressure pump designed to generate pressure from -14psi (-0.95bar) to 375psi (25bar). A high-quality screw press is designed for fine pressure adjustment, with an adjustment resolution up to10 Pa (0.1 mbar). A specially designed shut-off valve makes the pressure as stable as possible during calibration. A built-in gas-liquid isolator protects the pump from moisture and dirt to reduce the need for maintenance. Two hand-tight quick connectors installed on the pump allow easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches. The Additel ADT914 is an ideal comparison test pump for pressure instruments calibration.

The Additel ADT 914 Pneumatic Pressure Test Pump is designed to generate pressure from 95% vacuum to 375 psi (25 bar) for the application requiring accurate pressure testing and calibration. The Additel ADT914 can be used in calibrating pressure gauges, transmitters, or other pressure measuring instruments.
