all-sun EM2280 Ultrasonic Diagnostic Tool Mechanical Gas Air Leak Detector Vacuum Ignition Anodized Aluminum Probes Sound Trap
This turbulence or friction can then produces high frequency ultrasonic waves whose frequencies are normally higher than 20kHz and are far above the range of human hearing. The ultrasonic waves can travel in air and their intensity will attenuate rapidly as their propagation distance increases.Ultrasonic waves are highly directional, this directional aspect of ultrasonic waves allows one to isolate a suspect signature sound from other background noises and detect its exact location.
This Ultrasonic Diagnostic Tool operates on the principle mentioned above, it uses advanced ultrasonic sensing technology and converts inaudible ultrasonic sound into an audible sound which bears a close likeness to the natural incoming sample; for example, a gas leak sounds like a ” hiss ” and a defective bearing sounds like a ” clicking or chatter “. Since this tool is tuned to listen to the ultrasonic range, it is unaffected by everyday sounds such as wind, voices, and traffic. This Ultrasonic Diagnostic Tool is easy to carry and operate, and its detection result is accurate and reliable. It is very useful in preventive maintenance, trouble shooting, quality control and diagnostics in the automotive, industrial, manufacturing and process industries.

2.Gas and Liquid Turbulence
Moving parts, liquids and gases cause turbulence or friction.
