The Additel ADT 918 Pneumatic Pressure Test Pump is a hand-operated pressure generating tool, designed to deliver pressure from 95% vacuum up to 1500psi (100bar). A high-precision screw press is built in for fine pressure adjustment, delivering an adjustment resolution up to 10 Pa (0.1 mbar). A specially designed shut-off valve ensures maximum pressure stability during the calibration process. A built-in gas-liquid isolator protects the pump internals from moisture and dirt, reducing long-term maintenance requirements. Two pre-installed hand-tight quick connectors enable easy, tool-free connection and disconnection to the test circuit, with no need for PTFE tape or wrenches. The ADT 918 is an ideal comparative test pump for the calibration of pressure measuring instruments.

Purpose-built for applications requiring accurate pressure testing and calibration, the ADT 918 is suitable for calibrating large-size pressure gauges, pressure transmitters, and other pressure measuring instruments. Its rugged construction delivers reliable performance in both field and laboratory environments, with minimal maintenance requirements over its service life.
