The UL101 is a leak detector that maximizes the properties of ultrasound to find all turbulent flow leaks.

CTRL UL101 Leak Detection Advantages

Easy To Use Controls - Turn it on. Check the battery. Adjust sensitivity.

Locates Leaks Quickly - Detect air, gas, and steam leaks by simply pointing in the direction of potential faults.

Detects in Noisy Environments - Ultrasound ignores ambient audible sound, allowing small leaks to be detected in noisy plants.

Narrow Beam of Focus - The UL101 kit and its accessories narrows the range of focus for easily pinpointing the source of ultrasound.

Long Battery Life - A single 9-Volt battery operates the UL101 for 45-50 continuous hours. Other products use rechargeable batteries that require 3-5 hours of recharging after only 6 hours of use.

Extremely Sensitive - The UL101 is much more sensitive than its closest competitors.

Unmatched Signal-To-Noise Ratio - Other ultrasonic detectors produce a lot of white noise that can mask a leak. The UL101 eliminates the white noise.

Ultrasound Applications

Leak Detection
Compressed Air For Energy Savings Leaks account for 20% to 30% of the energy usage of a compressor.

Ultrasound is not affected by wind.

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

Steam Leaks
Improve steam system efficiency and save money.

Intrinsically Safe:
ANSI /UL 91 3-88, for DIVISION 1, CLASS I, Groups A, B, C and D, CLASS II , Groups E, F, G and CLASS III
It also complies with DIVISION 2, CLASS I, Groups A, B, C and D, CLASS II, Groups F, G, and CLASS III

Leak Detection

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.
