Marksman II can accurately “hear” leaks

Tracer Products manufactures a line of specialty products that quickly and effectively diagnose all types of leaks before they result in costly repairs.

The Tracerline Marksman II (P/N TP-9367) ultrasonic diagnostic tool is a highly accurate instrument that converts and amplifies inaudible ultrasonic sound into audible “natural” sound. Now service technicians can easily hear sounds that signify problems such as air brake leaks, compressed air leaks, vacuum leaks, and tire leaks—before they lead to major breakdowns.

This tool uses a two-tiered approach to ensure accurate diagnosis. The ultrasonic receiver converts inaudible sound into audible sound using heterodyne circuitry. Then its Sound Signature Technology fine-tunes the audible sound into the natural sound emitted by the leak itself. A five-LED signal-intensity indicator and audible alarm easily pinpoint the exact problem source.

The Marksman II is so sensitive it can detect leaks from orifices as small as 0.004 inches (0.1 mm) at 5.0 psi (34 kPa), from a distance of 12 inches (30 cm). An Internal Noise Control feature buffers ambient noise, making it ideal for use in even extremely noisy environments.

Ergonomically designed, this lightweight tool provides comfort and easy handling for prolonged use. The Marksman II comes complete with an ultrasonic receiver, headphones, hollow air probe, solid contact probe, and an ultrasonic emitter that helps locate faulty seals, gaskets, and weatherstripping in vehicle cabs, trailers and other non-pressurized enclosures. All components are packed in a sturdy carrying case.
