UL101 Leak Detector Kit

Tested by NASA and Defense

Once introduced to the CTRL UL101, a review panel that included astronauts were impressed with the UL101's sensitivity, size, and ease of operation. The first UL101 was delivered to NASA in 2001. There are now two UL101's on the International Space Station, were standard equipment on all of the Space Shuttles, and are currently relied upon by all US and Ally Military Branches for mission critical non-destructive testing and leak detection.

Leak Detection 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. 

Easily find leaks in a noisy environment. Ultrasound is very directional. Detect leaks from as much as 150 feet in some cases, depending upon the intensity of the leak. Pinpoint the leak to the exact location in seconds. 

Energy Savings
Reduce your compressor usage by 20% - 30%.

Ultrasound is not affected by wind.

Expensive Gas (Any Type)
Finding one Nitrogen leak has immediate ROI.

Steam Leaks / Steam Traps
Improve steam system efficiency and save money.
