"Hear" Problems Before They Become Breakdowns

Spectronics Corp (USA) has introduced the Spectroline® Marksman ultrasonic diagnostic tool, 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 compressed air leaks, electrical discharge, as well as vacuum, natural gas, propane, refrigerant, seal and gasket leaks.

This allows technicians to repair them long before they become major headaches. The Marksman uses a two-tiered process to ensure accurate diagnosis. First, the receiver unit converts inaudible sound into audible sound using a process known as heterodyning. Then, the receiver’s Sound Signal Technology fine-tunes the audible sound into the natural sound emitted by the defect itself. A 10-bar LED display indicates the intensity of incoming signals. Designed for optimal performance, the MDE-1000 Marksman Master Kit comes with a receiver, full-sized headphones, two probes, and an ultrasonic emitter that allows technicians to test for faulty seals, gaskets and weather stripping in doors, windows, ductwork and other unpressurized enclosures. When attached to the receiver, the 12-inch hollow probe accentuates air sounds, while the solid contact probe accentuates sounds of wear or grinding inside gears. Standard 9-volt alkaline batteries are included for both the receiver and the emitter. All components are packed in a sturdy storage case with foam insert.
