"We are extremely happy with its capabilities to find even the smallest leaks."
"If a leak makes bubbles using soap and bubbles, the UL101 will pick it up."
The CTRL UL101 ultrasound leak detector converts ultrasound produced by turbulent flow pressure and vacuum gas leaks at 40 kHz into the audible range. The converted ultrasound is output to an analog meter and a headset, so you can hear the leak.
Turn the UL101 Leak Detector on and adjust the sensitivity to eliminate ambient ultrasound. You will pick up the sound of a leak in your noisy plant very quickly. There is no need to adjust the frequency, calibrate, measure, or even squeeze a trigger.

Ultrasound Leak Detection Advantages
Detect Leaks in Noisy Environments - Ultrasound ignores ambient audible sound, allowing small leaks to be detected in noisy plants.
Detect Any Type of Gas Leak - Ultrasound is capable to detect any type of gas including freon, air, steam, nitrogen, etc.
Pressure & Vacuum Leaks - Both pressure and vacuum leaks can produce ultrasound.
Ultrasound is Directional - It is easier to locate a leak.
Low Costs - Compared to other technologies, ultrasound is quite inexpensive to implement, yet can be more effective for leak detection.
CTRL UL101 Leak Detector Advantages
Performance. The signal-to-noise ratio and sensitivity to ultrasound on the UL101 is unsurpassed (up to three times more sensitive than our closest competitors). It hears leaks other devices miss.
No requirement for recalibration. The UL101 is set to go at the factory and never needs to be returned for recalibration.
Battery life. The UL101 uses a standard 9-volt battery that gives 45-50 hours of continuous use which translates into 4-5 months of typical use. There is no forgetting to recharge batteries after every 8-hour shift.
Ease of use. The UL101 requires no decibel or other unnecessary settings that, if incorrect, would make the device less likely to detect the targeted ultrasound. Unnecessary bells and whistles only complicate the usage. With the UL101, turn it on and go. Just adjust the sensitivity to eliminate background noise with a simple volume-like knob.
Application expansion. The same UL101 Receiver is used in the Air Audit Kit as well as the full kit for troubleshooting, predictive maintenance, and all of the other applications suitable for ultrasound. There is no need to purchase multiple devices.
Ability to differentiate background noise from detectable ultrasound. Since the UL101 is an analog device, no "white" noise or background noise is introduced into the device because of digital meters and readouts. The methodology used on the UL101 to bring ultrasound into the human audible range is superior. With the UL101, if there is no ultrasound present you will hear nothing but silence, minimizing false positives.
