A high-quality screw press is designed for fine pressure adjustment, with an adjustment resolution up to 0.1 Pa (0.001 mbar). The 901A and 912A are very stable low pressure calibrators. They make 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. These pumps do not use a check valve and are remarkably stable. Two hand-tight connectors installed on the pumps allow easy connecting and disconnecting without the need for PTFE tape or wrenches. The 901A and 912A are ideal comparison test pumps for low pressure applications.
