1. DEFINITION OF THE ATEQ F620
The ATEQ F620 is a compact air/air
leak detector used to test the air-
tightness of parts. 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.
