Fluke ULD-410 ULTRASONIC LEAK DETECTOR

The ultimate ultrasonic diagnostic tool – HVAC/R, mechanical and electrical inspection and troubleshooting

The Amprobe ULD-410 model comes with the ULD-400-R Receiver unit and accessories. The Receiver provides the strength of the leak through a user interface on a large LCD display bargraph and identifies the source of the leak by listening to the converted audible sound emitted via the headphones.

When equipment begins to fail due to an air or gas leak or vibration, or electrical discharge, the leakage point emits an ultrasonic sound wave that is above the natural range of human hearing. The ULD410 converts this ultrasonic sound into a signal that can be used to pinpoint the exact location of the equipment failure.

Find leaks even in noisy environments

In some situations, there might be strong ultrasonic noise generated by running machinery, motion sensors or other equipment. This noise will cause the Receiver to read the maximum signal strength on the display regardless of the sensitivity settings and make it unusable for detecting leaks. The Filter function was designed for these situations. Simply press the Filter button and the Receiver will automatically detect and and filter out up to three main noise frequencies.

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.
