PREAMBLE
1. DEFINITION OF THE ATEQ F CLASS
The ATEQ F CLASS are compact air/air
leak detectors used to test the air-
tightness of parts on production lines.
They are 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.
