The PATENTED AccuTrak represents state-of-the-art technology for pinpointing leaks in air conditioning and refrigeration systems. AccuTrak is extremely sensitive to the ultrasonic sound of a turbulent gas leak. Using a technique called “heterodyning” it translates the sound to a lower frequency which your ear can interpret.

           

Model PD-100

AccuTrak maintains the original sound characteristics making it possible to distinguish leaks from other competing background sounds. AccuTrak is so sensitive you can actually hear the blink of an eye, yet most background noise will not interfere with detection accuracy.
