Experts in Acoustic Ultrasonic Leak Detection

UL101 Leak Detector

Easily find air and steam leaks in a noisy environment. Slash energy costs.

The UL101 Leak Detector uses acoustic ultrasound technology to quickly locate the ultrasound waves produced by compressed gas/air leaks, steam trap leaks, and vacuum leaks. It can also detect issues in bearing lubrication. 


Simply aim the leak detector in the direction of the piping and adjust the sensitivity to pinpoint the location of any leak with turbulent flow. 


  • Leak detection (vacuum & pressure) 

  • Electrical inspection (partial discharge detection)

  • Valve leaks & steam trap inspection

  • Precision bearing lubrication checks
