The NEW MI-3000

One audiometer, two distinct versions, offers versatility and ease-of-use at a lower price

The MI-3000 Standard Version

The standard MI-3000 audiometer is an economical, manually operated audiometer that tests frequencies from 125 Hz to 8000 Hz, including standard inter-octave frequencies. It is small and light enough to be portable, yet large enough to provide easy access and operation of all audiometer controls.

The MI-3000 Plus Version

In addition to the standard features, the MI-3000 Plus offers flexible communication capabilities via the included Monitor Basics software. This software enables control of the audiometer by a Windows-based computer, allowing the operator to set up, start, and visually track the progress of automatic threshold or screening tests. Completed tests can be printed via the computer’s printer.

Potential users include:
Doctors offices, schools, small industries, hospitals, community health screening organizations
