leak testing

  • AccuTrak VPE Ultrasonic Leak Detector:

    The AccuTrak VPE Ultrasonic leak detector is extremely sensitive to the ultrasonic sound of a turbulent gas leak.  Using a technology called "Heterodyning" it translates the sound to a lower frequency which your ear can interpret.  AccuTrak maintains the original sound characteristics making it possible to distinguish leaks from other competing background sounds. 

    Includes everything you need: Ultrasonic detection unit, headset, wave guide, padded hard carry case, 9V DC battery and user manual.


    • Leak Detection: Air, Vacuum, Refrigerants, Any gas.
    • Diagnose thermal expansion valves in just 5 minutes.
    • Valves: Detect - hear internal leakage in any type of valve.
    • Bearing Wear: Hear wear & lubrication problems before damage is done.
    • Steam Traps: Detect live steam loss in seconds.

    Capabilities and benefits of the AccuTrak Ultrasonic leak detector:

    • 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.
    • Adjustable Sensitivity allows operator to quickly identify leaks from a distance and then zero inn on the exact location of the leak.
    • Easily detects any gas that generated ultrasonic sound during flow - including vacuum leaks.
    • Detecting leaks equivalent to 1.5oz/year of refrigerant. 
    • Not affected by wind or high concentrations of leaked gas or refrigerants.
    • The quickest, most cost effective way to find leaks. 
    • Save time and money on energy use, reduce costs on product loss.
    • Non-destructive, non-invasive testing. 
    • Compact with one hand operation.
