Ultrasonic diagnostic tool lets techs ‘hear’ problems

The tool allows service technicians to hear sounds that signify problems such as tire leaks, air brake leaks, compressed air leaks, vacuum leaks and EVAP system leaks. They can repair these issues before they lead to major breakdowns.

The Marksman II uses an ultrasonic receiver that makes inaudible sound audible using heterodyne circuitry. Sound Signature Technology fine-tunes the audible sound into the natural sound emitted by the leak itself.

A 5-LED signal-intensity indicator and audible alarm pinpoint the exact problem source. Tracer says the Marksman II is so sensitive that it can detect leaks from orifices as small as 0.004 inch (0.1 mm) at 5.0 psi (34 kPa), from a distance of 12 inches (30 cm).
