Ultrasonic leak detector for energy conservation

Exair's Ultrasonic Leak Detector (ULD) is a handheld 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 6.1 m away.

High-pressure air expanding to atmosphere creates high-frequency turbulence that the ULD converts into an audible tone that can be heard through the supplied headphones. Background plant noise is filtered out using the three sensitivity settings of X1, X10 and X100 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 make out intense background noise are provided.

The Model 9061 comes complete with a hard-shell plastic case, headphones, parabola, tubular adapter, tubular extension and 9 V battery.
