DEFINITION, CHARACTERISTICS AND MEASUREMENT
PRINCIPLES
1. DEFINITION OF THE ATEQ 6
TH
SERIES
The ATEQ 6
th
series is a state of the art
touch color screen compact air/air leak
detectors designed to test the air-
tightness of parts on production lines. It is
specially adapted for automatic and
semi-automatic workbenches. The
method used is based on the
measurement of a small variation or drop
in differential pressure between the test
and reference parts, when both are filled
to an identical pressure.
