The Additel ADT 912A Low Pressure Test Pump is a manually operated pressure pump capable of generating pressure from -14 psi (-0.95 bar) to 60 psi (4 bar). It features a high-precision screw press for fine pressure adjustments, offering a resolution of up to 0.01 Pa (0.0001 mbar). To ensure maximum stability during micro-pressure calibration, the pump is equipped with an isothermal bellows chamber that minimizes the impact of temperature fluctuations and a specially designed shut-off valve that maintains consistent pressure. A built-in gas-liquid isolator helps protect the pump from moisture and contaminants, reducing maintenance needs. Additionally, two hand-tight connectors allow for quick and secure connections without requiring PTFE tape or wrenches. The ADT 912A is an excellent choice for low-pressure comparison testing applications.

Choosing a type of female-threaded fitting. Here’s what each option means:
- 1/4 NPT female – A female-threaded fitting with a 1/4-inch National Pipe Taper (NPT) thread standard, commonly used in the United States for fluid and air connections.
- 1/2 NPT female – A similar fitting but with a larger 1/2-inch NPT thread size.
- 1/4 BSP female – A female-threaded fitting with a 1/4-inch British Standard Pipe (BSP) thread, which is commonly used in Europe and other regions.
- M20x1.5 female – A metric female-threaded fitting with a 20mm diameter and a 1.5mm thread pitch, commonly used in machinery, hydraulics, and industrial applications.
