The Spectroline MDE-2000NC Marksman II ultrasonic diagnostic tool converts and amplifies inaudible ultrasonic sound into audible “natural” sound. This highly advanced tool allows the aircraft technician to “hear” even the smallest brake, vacuum, tire, and other pressurized leaks…before they lead to major breakdowns. The contact probe pinpoints wear or damage to gears, bearings and other internal components…without disassembly. It uses a two-tiered approach to ensure accurate diagnosis. The receiver converts inaudible ultrasonic sound into audible sound using heterodyne circuitry. Then, its unique 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 locates the exact source of the problem. An Internal Noise Control (INC) feature safeguards against ambient noise and the Automatic Gain Control (AGC) circuitry automatically adjusts to optimize signal sensitivity during every inspection. It comes complete with an ultrasonic receiver, full-sized, heavy duty, noise-canceling headphones, a hollow air probe, a solid contact probe and an ultrasonic emitter that helps locate faulty seals, gaskets and weatherstripping in doors, windows, trunks and other non-pressurized enclosures. All components are packed in a sturdy carrying case. For more information visit www.spectroline.com.
