The patented Superior AccuTrak® VPE-GN “Gooseneck” Ultrasonic Leak Detector is a cutting-edge, non-invasive device designed to identify both pressure and vacuum leaks of any gas. The AccuTrak® VPE-GN excels at locating leaks in systems such as air conditioning, refrigeration, and automotive applications. Its unique 9½” flexible gooseneck enhances detection in areas that are difficult to access. AccuTrak® Ultrasonic Leak Detectors are highly sensitive to the ultrasonic noise produced by turbulent gas leaks. Utilizing advanced "heterodyning" technology, these devices convert ultrasound into a lower frequency that can be heard by the human ear. The VPE-GN Ultrasonic Leak Detector preserves the original sound characteristics, allowing users to differentiate leaks from other ambient noises.
