Congratulations on your purchase of the Robinair TruTrack Ultrasonic
Leak Detector, the only ultrasonic instrument specifically designed for air
conditioning and refrigeration leak detection. TruTrack is the ideal tool
for detecting both vacuum and pressure leaks of any refrigerant. Because
this instrument detects sound, it is gas-independent. Even dry nitrogen
leaks can be detected.
The TruTrack Ultrasonic Leak Detector locates leaks in gas-saturated
areas, in windy conditions, and in systems under negative pressure
(vacuum states). It eliminates the need to use tracer gases since it uses
sound waves to locate leaks.
Description
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.
