Air: -6psi to 6psi
The Additel 901A Low Pressure Test Pump is a hand operated pressure pump designed to generate pressures from -6 psi (-0.4 bar) to 6 psi (0.4 bar). A high-quality screw press has been designed for fine pressure adjustment, with an adjustment resolution up to 0.1 Pa (0.001 mbar). The 901A is a very stable low pressure calibrator that makes use of an isothermal bellows chamber which is designed for reducing the possible effects of environmental temperature change.
Most pumps make use of a check valve (non-returning valve) that are not well insulated which will cause large fluctuations in pressure with a change in ambient temperature or when the unit is touched. The 901A does not use a check valve and is remarkably stable.
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 Additel ADT901A pump is an ideal comparison test pump for low pressure applications, featuring:
- Great stability and high resolution
- Minimal maintenance
- Hand-tight quick connectors
- Lightweight and portable (only 1.6kg)
- Easy to use
- 1 year warranty
