Description

Application areas

Hand test pumps serve as pressure generators for the testing,

adjustment and calibration of mechanical and electronic

pressure measuring instruments through comparative
measurements. These pressure tests can take place in the
laboratory or workshop, or on site at the measuring point.

Easy operation

If one connects the test item and a suciently accurate

reference measuring instrument to the hand test pump,
on actuating the pump, the same pressure will act on both
measuring instruments. By comparison of the two measured
values at any given pressure value, a check of the accuracy

and/or adjustment of the pressure measuring instrument

under test can be carried out. In order to approach the

measuring points exactly, the hand test pump features a ne
adjustment valve.

Pneumatic hand test pump model CPP7-H

Easy handling

The CPP7-H is a pneumatic hand test pump for low-pressure
ranges up to 7 bar (101.5 psi), with switching to vacuum
generation down to -800 mbar (-11.6 psi). The maximum
pressure or vacuum achievable is dependent upon the
connected test volume.
Through the smooth pressure generation and the integrated

ne adjustment valve, very small positive or negative

pressures in the mbar range can be set safely and precisely.

Via a T-connector with a hose connection, the test item and
the reference measuring instrument can be easily connected.
