The MI-5000B Series II Microprocessor Audiometer is one of the lowest-priced field serviceable microprocessor audiometers available today. It administers computerized tests securing valid, reliable data quickly and cost effectively. It is very easy to understand and use, and can be used either alone, or interfaced with an external printer or computer. Interface settings can be changed by the operator. Tones are generated and controlled entirely by digital circuits, allowing output levels of the MI-5000B to be adjusted by through secured keyboard entry. The LCD display simultaneously shows all thresholds established for both ears, as well as on-going test conditions.
