The UG Sound Generator and the UL Detectors form a non-invasive leak detection system capable of finding leaks in enclosures, such as buildings, vessels, automobiles, walk-in freezers, or any other container that needs to be leak-free.

The Sound Generator is used to “pressurize” rooms and enclosures with its sound. This sound is above the human hearing range, and cannot be heard. It can penetrate through minute cracks, even ones that are not directly behind the leak point, and exit through it. It can thus trace the path air, or water will take to cause a leak. The Detector receives the ultrasonic sound that escapes from the leak point, processes it and displays its strength. The bigger the leak is, the higher the volume in the headset.
