Additel 916A
The 916A Pneumatic Pressure Test Pump is a hand-operated pressure pump designed to generate pressure from 95% vacuum to 600psi (40bar). 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 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 916A is an ideal comparison test pump for pressure instrument calibration. Portable, only 5.9 lb.

Additel 917
