Additel 912A Low Pressure Test Pump
The 912A Pneumatic Pressure Test Pump is a hand operated pressure pump
designed to generate pressure from 95% vacuum to 60psi (4bar).
A high-quality screw press is designed for fine pressure adjustment, with an adjustment resolution up to 0.1 Pa (0.001 mbar).
912A is a very stable low pressure calibrator. It 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) and are not well insulated which
will cause large fluctuations in pressure with a change in ambient
temperature or when the unit is touched.
The 912A does not use a check valve and is remarkably stable.
hand-tight connectors installed on the pump allow easy connecting and
disconnecting to the test pump without the need for PTFE tape or
The 912A is an ideal comparison test pump for low pressure application.
