These high-quality headphones eliminate all background noise, allowing a technician to effectively find the smallest leaks - even in very loud environments. You can choose the standard style professional headphones, or the hardhat compatible version - same price!The Patented Superior AccuTrak VPE-GN Gooseneck is a state-of-the-art non-invasive leak detector that can detect both pressure and vacuum leaks of ANY GAS. The AccuTrak VPE-GN is ideal for pinpointing leaks in air conditioning, refrigeration, automotive and other systems. The new 9 flexible Gooseneck provides better detection capabilities in hard-to-reach places. 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. 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.NEW! 3rd Generation VPE Features 20% Greater Sens
