TROUBLESHOOTER
000031 Standard Model
000033 Intrinsically Safe Model
The UL101 Troubleshooter includes all the components of the UL101 Leak Detector and more, further extending the application of your device. From leak detection to lubrication, the UL101 Troubleshooter is a fully integrated solution for a variety of issues you may encounter within your system.
The CTRL UL101 Troubleshooter converts ultrasound signals produced by industrial machinery and vehicles into easily recognizable audible sounds, so the user can evaluate the condition of individual components, even in extremely noisy plant environments. The CTRL UL101 Troubleshooter is used worldwide for condition-based monitoring maintenance, quality control, and leak detection.

Benefits of UL101 Acoustic Ultrasound Listening Devices
Ease-of-use
Simply adjust the sensitivity on the UL101 Troubleshooter’s handheld receiver to pinpoint the leak; scan areas from up to 300 feet away with the PowerBeam 300 parabolic accessory.
Directionality
Ultrasound travels in linear paths and doesn't tend to travel around corners or reflect. Using CTRL’s acoustic ultrasound listening products, leaks are not easily masked.
No calibration needed
Acoustic ultrasound is used for indication and location, not leak measurement. Our leak detectors are ruggedized for use in the most caustic of environments, including power plants
Sensitivity
Our UL101 Troubleshooters can find leaks faster and more accurately. Your systems can now run at normal and even improved vacuum levels to improve power turbine efficiency.
Costs
The cost of a high end ultrasound detector is 3 to 5 times less than the cost of a helium leak detection system. CTRL’s UL101 products are priced competitively compared to industry leaders, require less training, and are faster to use.
