ADT-912 Pneumatic Low Pressure Test Pump 4 bar

The ADT-912 Pneumatic Pressure Test Pump is a hand operated pressure pump designed to generate pressure from 95% vacuum to 4bar. A high-quality screw press is designed for fine pressure adjustment, with an adjustment resolution up to 0.001 mbar. The ADT-912 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 ADT-912 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 ADT-912 is an ideal comparison test pump for low pressure application.
