Robinair 16455 TruTrack Ultrasonic Leak Detector

The TruTrack Ultrasonic Leak Detector is a non-invasive detector that locates both pressure and vacuum leaks. It represents an advanced level of technology, because it is a listening device that detects ultrasonic sounds, not chemical refrigerants.

A leak is any unwanted flow of a substance out of a system, or in a vacuum, into a system. Friction in flow generates sound. For example, water flowing in pipes creates sound just as air leaking out of a tire. The sound humans can hear represents less than a third of the total spectrum of frequencies generated. The sound made by small leaks is mostly ultrasonic-above the human hearing range.

The TruTrack Ultrasonic Leak Detector "hears" the sound of the turbulent gases moving through the opening at the leak site and displays the strength of the sound. The larger the leak, the stronger the indication on the detector. The detector also produces an audio reproduction of the leak sound. The intensity of the audio changes proportionally to the intensity of the leak sound.
