OVERVIEW

Pressure / Process Calibration Equipment

The 912A Pneumatic Pressure Test Pump is a hand operated pressure pump designed to generate pressure from

95% vacuum to 60 psi (4 bar). A high-quality screw press is designed for ne pressure adjustment, with an adjustment

resolution up to 0.1 Pa (0.001 mbar). The 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 uctuations

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. 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 912A is an ideal comparison test pump for low
pressure application.
