OVERVIEW

The 901 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 ne pressure adjustment, with an adjustment resolution

up to 0.1 Pa (0.001 mbar). The 901 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 901 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 901 is an ideal comparison test pump for low pressure applications.

FEATURES SPECIFICATIONS

Portable: Only 3.5 lb (1.6 kg)
Adjustment Resolution

0.1Pa (0.001 mbar); Specially designed screw press

for ne pressure adjustment.

Great Stability

Isothermal chamber: the pressure chamber is

insulated to reduce the inuence 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.

Easy-to-use

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.
