AccuTrak, VPE-GN, Gooseneck Ultrasonic Leak Detector Standard KitIncludes:VPE-GN Leak DetectorHeadsetBatteryHard CaseWaveguideThe Patented Superior AccuTrak VPE-GN "Gooseneck" represents state-of-the-art technology for pinpointing leaks in air conditioning and refrigeration systems. The new 9-1/2" flexible Gooseneck provides better detection in hard-to-reach places and is great for automotive applications too. 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.Superior AccuTrak advanced patented technology has never been so versatile! The AccuTrak VPE-GN Standard Kit offers all the functionality and features of the VPE Basic Kit – but with the sensor on the end of a 9-1/2" long flexible GooseNeck to get into all those hard-to-reach places.The VPE-GN Standard Kit is great for technicians in the Automotive industry, or any others who need to find tough leaks or other airborne ultrasound in tight spaces, behind obstructions, or inside an assembly. As with all AccuTrak instruments, the VPE-GN finds leaks for any kind of gas or refrigerant without changing tips or components. Works equally well to find compressed air leaks, nitrogen leaks – even vacuum leaks! AccuTrak can find leaks as small as the equivalent of 1.5 oz per year of refrigerant, or can hear a 5 psi leak up to 30 feet away.Features:Gooseneck Configuration: Allows operator to get accurate readings in hard to reach places.Audio Output: 0 Hz to 4 kHz Natural Sound conversion allows you to Hear the Leak and distinguish leaks from mechanical or other background ultrasound.Visual Output: 10 element bar graph provides quick and intuitive visual indication to presence of and relative strength of ultrasound.Adjustable Sensitivity: Allows operator to quickly identify leaks from a distance and then zero in on the exact location of the leak.Applications:Leak Detection: Air, Vacuum, Refrigerants; any gas!Capabilities:Capable of detecting a 5 psi leak out of a 0.005" (5/1000 inch) hole, 20 to 30 feet away depending on background noise.Easily detects any gas that generates ultrasonic sound during flow - including vacuum leaks.Capable of detecting leaks equivalent to 1.5 oz/year of Refrigerant.Works equally well for compressed Air or Nitrogen.Not affected by wind or high concentrations of leaked gas or refrigerant.AccuTrak VPE Advantages Versus Sniffers:Is a much more accurate and reliable instrument for detecting single and multiple leaks.Can detect any type of refrigerant gas including nitrogen.Detects both vacuum and pressure leaks.Is effective in gas saturated areas and under windy conditions.Does not require the introduction of tracer gases into the system, which can be ozone depleting when vented and can also be harmful to ones health.Is battery powered for cordless operation.AccuTrak VPE Advantages versus other Ultrasonic Leak Detectors:Is #1 in technology. We wrote the book on ultrasonic leak detection, our patented instruments lead the industry!Is the original! it is not a copy.Is the most durable unit available, with the best warranty. The face of the unit is sealed with no pin holes/speakers for foreign objects to enter.Has more dynamic range and wont overload in loud areas.Gives true audio sound reproduction instead of the "beeps and squeals" of other instruments.
