The Patented Superior AccuTrak® VPE-GN "Gooseneck" represents state-of-the-art technology for pinpointing leaks in air conditioning and refrigeration systems. The new 9½" flexible Gooseneck provides better detection in hard-to-reach places, and is great for automotive applications too.
AccuTrak® is so sensitive you can actually hear the blink of an eye, yet most background noise will not interfere with detection accuracy. Like all Superior AccuTrak® instruments, the VPE-GN easily detects leaks of ANY gas or refrigerant, compressed air, and even vacuum leaks. AccuTrak® is extremely sensitive to the ultrasonic sound of a turbulent gas leak. Using the latest "heterodyning" technology it translates the sound to a lower frequency which your ear can interpret. The VPE-GN maintains the original sound characteristics making it possible to distinguish leaks from other competing background sounds.
