A high-quality screw press is designed for fine pressure adjustment, with an adjustment resolution as high as 0.01 Pa (0.0001 mbar).
To make pressure setting as stable as possible during micro-pressure calibrations, an isothermal bellows chamber has been incorporated into the design for reducing the heating and cooling effects caused by environmental temperature change.
There is no non-return valve fitted which is usually used on other types of hand pumps, therefore the ADT-901 requires minimal maintenance.
Two hand-tight connectors fitted to the pump provide easy connecting and disconnecting to the test pump without the need for PTFE tape or spanners. The ADT 901 is an ideal comparison test pump for low pressure applications.

0.01Pa (0.0001 mbar) Specially designed screw press for fine pressure adjustment
Isothermal chamber: the pressure chamber is insulated to reduce the influence of environmental temperature changes.
Specially designed bellows reduces leakage to guarantee excellent stability.
Durable and minimal maintenance
Without non-returning valve that is usually used on trouble some hand pump.
Easy to use
Pressure could be set and adjusted precisely and quickly through a simple turn of the handle.
Allows easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches.
The ADT901 low pressure calibration pump is designed for low pressure applications requiring precise testing and calibration. You can use this pump for calibrating low pressure gauges, switches, shut-off valves, transmitters or any other low range pressure measuring instruments.
