Technicians can “hear” the smallest compressed-air, natural-gas, propane-tank, vacuum, and steam leaks before problems arise with the MDe-2000 NC Marksman II ultrasonic diagnostic tool. The tool converts and amplifies inaudible ultrasonic sounds into audible sounds. A two-tiered approach diagnoses problems: The receiver’s heterodyne circuitry converts inaudible sound into audible sound and then fine-tunes the audible sound into the natural sound emitted by the leak itself. A five LED signalintensity indicator and audible alarm pinpoint the exact source of the problem. An internal noise-control feature safeguards against ambient noises. The tool comes with an ultrasonic receiver; full-sized, heavy-duty, noisecanceling headphones; a hollow air probe; a solid contact probe; and an ultrasonic emitter that locates faulty seals, gaskets, and weatherstripping in doors, windows, ducts, and other nonpressurized enclosures.
