The UL101 is a unique diagnostic tool for the automotive industry and aftermarket.Through the detection of ultrasonic sound, the UL101 is used to inspect and check such items as: air brake systems, bearings, gear trains, cam and tappet assemblies, internal combustion engine valving and piston blow-by, gaseous piping and dueling, seals in refrigerated van bodies, air ducts, hydraulic systems and many other components.

Except for their frequencies, ultrasonic waves are exactly the same as their audible counterparts. Audible sound will propagate and compound itself through the vehicle making it difficult to locate the source even with a stethoscope. Because ultrasonic waves attenuate faster than lower audible frequencies, it is much easier to pinpoint the source of the ultrasound. Moreover, there is usually much less noise interference. Conversation and background noises are not heard by the receiver. Extremely minute sounds can, therefore, be detected, analyzed, and the exact location determined.
