AccuTrack Ultrasonic Leak Detector

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.
