Exair's Updated Ultrasonic Leak Detector (ULD) is a handheld instrument designed to help locate the source of leaks in a compressed air system. With this tool, testing the various unions, pipes, valves, and fittings of a complete installation can be done at distances up to 20' away. The ULD can detect the vibrations of high pressure gases, creating an audible sound through supplied headphones as well as indicating intensity via front-facing LED display as it moves closer to the leak origin. Adjustments can be made to filter out background noise with "+" or "-" buttons for fine-tuning sensitivity. The updated ULD offers an increased ability to detect leaks in hard-to-reach areas while complying with the IEX 61326-1 standard.
