For pinpointing leakages, especially in loud ambiance, where the leak is not hearable by ear as well for locating untight places in compressed-air systems where compressed-air escapes in a noiseless frequency and for checking internal sealing of e. g. cockpits, pressure chambers etc. The noise, which is created by air escaping from a leak, is detected by an ultrasonic receiver and converted in hearable noise and an optical indication.
Leakages with more than 0.1 mm and 1 Bar can be detected with the unit. For leakages with a diameter smaller than 0.1 mm, a higher pressure is recommended. For leakages at hard to reach places a gooseneck (260 mm) or a ultrasonic parabolic reflector (up to distance of 20 m) are optional available.
