EXAIR Ultrasonic Leak Detector Model 9207

The Model 9207 Ultrasonic Leak Detector (ULD) is a hand-held, high quality instrument that can locate costly leaks in a compressed air system. When a leak is present, an audible tone can be heard (with the use of the included earbuds) and the LED display will light. Testing the various unions, pipes, valves and fittings of a complete installation can be done quickly and effectively at distances up to 20' (6.1m) away! The ULD can be adjusted to filter out background noise using a "+" or "-" sensitivity adjustment. The parabola or tubular extension can be attached to the ULD to mask out intense background noise.
