Ultrasonic
detection …
As a gas or liquid passes through a small restrictive opening,
ultrasonic noise is created. While this noise is imperceptible
to the ear it is very easily located by the Leak Detector using
the ultrasonic probe.
The ultrasound is indicated by an LED-array and an audible tone
through the earphone headset. As the instrument is moved closer
to the ultrasonic source more LED's will light up. Simultaneously,
the frequency of the tone rises.

The ultrasonic leak detector is particularly adapted to the
control of the flexible airtightness during the vacuum processes
like vacuum infusion, vacuum moulding and RTM or RTM LIGHT.
