With the EXAIR Ultrasonic Leak Detector you are able to detect costly compressed air leaks. Up to 30% of the compressed air produced can be wasted through leaks in the piping and fit work. Many of these leaks are so small that they are barely noticeable. The Ultrasonic Leak Detector can convert the ultrasound that these leaks cause into the human audible pitches. The ULD can detect leaks up to 6 meters away. Comes in a sturdy case including parabolic attachment, hose and hose connection as well as a headset.
