Additel ADT901B Pneumatic Pressure Test Pump (-0.4 bar to 0.4 bar)
Model No: ADT901B
Order Code: ADT901B-N
Warranty: 1 Year
Stock Status : Instock
The 901B Low Pressure Test Pump is a hand operated pressure pump designed to generate pressures from -6 psi (-0.4 bar) to 6 psi (0.4 bar). A high-quality screw press is designed for fine pressure adjustment, with an adjustment resolution up to 0.1 Pa (0.001 mbar). The 901B 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 901B 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 901B is an ideal comparison test pump for low pressure applications.
● Portable: Only 3.5 lb (1.6 kg)
● Adjustment Resolution
0.1Pa (0.001 mbar); Specially designed screw press for fine pressure adjustment.
● Great Stability
Isothermal chamber: the pressure chamber is insulated to reduce the influence from environmental temperature changes. Specially designed bellows minimize leakage to guarantee excellent stability.
● Durable and Minimal Maintenance
Without non-returning valve that is usually used on troublesome hand pump.
Pressure could be set and adjusted precisely and quickly through a simple turn of the handle.
● Hand-tight Quick Connectors
Allows easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches.
