The Additel ADT 912 Low Pressure Test Pump is a hand operated pressure pump designed to generate pressure from -14psi (-0.95bar) to 60psi (4bar). A high-quality screw press is designed for fine pressure adjustment, with an adjustment resolution up to 0.01 Pa (0.0001 mbar). To reach the pressure as stable as possible during the micro-pressure calibration, an isothermal bellows chamber is designed to reduce the possible heat effects caused by environmental temperature change, and 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 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 PTFE tape or wrenches. The ADT 912 is an ideal comparison test pump for low pressure application.
