What our customers say about the UL101 Ultrasound Leak Detector:

  • "We needed the UL101 for our 2G areas, but because it was so easy, I stopped using my other detectors."
  • "I can carry it with me anywhere; it's so small."
  • "It works!"
  • "I love it. It's so much easier than our ..." $10,000 detector.
  • "The guesstimator for quantifying leaks was so wrong on our other ultrasonic leak detectors; we just can't see why you would continue to use anything but the UL101. It's so easy to find the leaks."
