instrument that it says converts and amplifies inaudible ultrasonic sound into audible “natural” sound. Tracer says the product allows technicians to hear sounds that signify problems such as air brake leaks, compressed air leaks, vacuum leaks, tire leaks and much more.
The Marksman II uses a two-tiered approach to ensure accurate diagnosis, Tracer says. The ultrasonic receiver converts inaudible sound into audible sound using heterodyne circuitry. Then, Tracer says its 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, the company says.
Tracer says the Marksman II can detect leaks from orifices as small as 0.004 in. (0.1 mm) at 5.0 psi (34 kPa), from a distance of 12 in. (30 cm).
The Marksman II comes with an ultrasonic receiver, headphones, hollow air probe, solid contact probe and an ultrasonic emitter that helps locate faulty seals, gaskets and weather stripping in passenger cabs, trailers and other non-pressurized enclosures, the company says.
