Ultrasonic Leak Detector

EXAIR’s new Ultrasonic Leak Detector (ULD) is a handheld, high quality instrument that can locate costly leaks in a compressed air system. Leaks often account for over 30% of the compressed air consumed in industrial plants. A huge annual air savings worth tens of thousands of dollars is possible when the leaks are located and repaired. Testing the various unions, pipes, valves and fittings of a complete installation can be done quickly and effectively at distances up to 20 feet away.

High pressure air expanding to atmosphere creates high frequency turbulence that the ULD converts into an audible tone. Background plant noise is filtered out using the three sensitivity settings of XI, XI0 and XI00 along with an on/off thumb wheel for fine sensitivity. As the ULD moves closer to a leak, more LEDs on the display light to confirm the source of the leak. A parabola attachment to pinpoint leaks and a tubular extension to mask out intense background noise are provided.
