Ultrasound Leak Detector Solutions


Airborne and structure-based (A&SB) ultrasound detection can be used to easily locate leaks within a noisy environment. CTRL Systems has designed an easy-to-use device that is more sensitive than any other ultrasound detector in the world. With the UL101 Leak Detector and our conditioned based monitoring technology, you can detect leaks from up to 150 feet away and pinpoint their exact location in mere seconds. The UL101 Leak Detector is not affected by loud industrial environments and can be used in windy conditions. It can be used to locate any type of turbulent compressed gas or vacuum leak. Applications include: compressed air energy swings (reduce compressor usage by 20-30%!), vacuum leak detection, HVAC leak detection, dry sprinkler inspection, steam system inspection, cabin testing, and many more!


Ultrasonic Leak Detector Benefits


Other devices require you to be within 1 to 2 feet, to adjust the frequency, to only use for a particular type of gas, etc. The design of the UL101 is "keep it simple." CTRL has designed an easy to use device that is more sensitive than any other and fits in the palm of your hands.

With the UL101 Leak Detector, you can easily find leaks in a noisy environment. Acoustic ultrasound has a very impressive range and can detect leaks from as far as 150 feet, depending upon the intensity of the leak, pinpointing the leak to the exact location in seconds.
