Find costly leaks in active compressed air systems

Easy inspection and troubleshooting

The Amprobe ULD-405 Ultrasonic Leak Detector is a diagnostic tool that hears what you can't. When equipment begins to fail due to an air leak or vibration, the leakage point emits an ultrasonic sound wave that is above the natural range of human hearing. The ULD-405 Ultrasonic Leak Detector converts this ultrasonic sound into a signal that can be used to pinpoint the exact location of the equipment failure. Find air leaks that drop down performance and incur additional power consumption, requiring more energy to compensate lost pressure. See the strength of the leak clearly on the large LCD bargraph and identify the source of the leak by listening to the converted audible sound emitted via the earbuds.

Visual and audible leak pinpointing

While scanning a target area with the Receiver's microphone sensor, the displayed bargraph will indicate proximity to the source of the leak. Plug the headphones into the Receiver to audibly hear the leak and verify its source. For example, air leaks will produce more of a hissing sound while electric discharge manifests in a ticking sound.

Reduce your utility bill

Air leaks can have a huge impact on the energy efficiency of your whole system. The ULD-405 will help you troubleshoot problem areas where air leaks have gone undetected, reducing your overall financial costs.

Kit Components

The ULD-405 comes supplied with additional Receiver accessories that are helpful in leak identification. Plug the headphones into the Receiver to audibly hear the leak and verify its source (for example hissing sound of an air leak versus ticking sound of an electric discharge). Use the Parabola attachment in situations where there is a high level of background noise to help direct the ultrasound towards the sensor. Use the Tubular Extension with the Adapter in hard to reach areas for additional reach.
