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 suciently 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.
