Monitor Instruments 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.


Monitor Instruments MI-5000B

a2The 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.


SMART TONE Automatic Audiometer

a3The SMART TONE Automatic Audiometer uses the latest technology to deliver quick and accurate audiograms via an extremely easy-to- use touchscreen with an intuitive icon interface. Gone are the days of “cheat sheets” and having to memorize multiple key functions—now you can simply sit down and use it!



Tremetrics RA300 Digital Audiometer

a4The affordable RA300 brings a new level of automation to a broad range of hearing screening programs. Small occupational health departments as well as hospital/community health programs can now benefit from Tremetrics’ proprietary test paradigm which produces valid test results in as little as three minutes. The compact unit includes an easy to read, backlit display and outputs data to standard printers or PCs through its RS232C port.



Calibration Monitor




The MI-300 Calibration Monitor performs a quick and efficient daily biological calibration check of your audiometer, as required by OSHA. Its lightweight and durable construction will insure years of trouble-free operation.



D-Check Bio-Acoustic Simulator

a6The D-Check Bio-Acoustic Simulator performs dependable daily calibration checks of the SMART TONE Automatic Audiometer, and can be used for OSHA, MSHA, or DOT hearing programs.Because the D-Check is powered by the SMART TONE audiometer, there is no need to worry about battery life. This advanced design simplifies the daily check and offers greater reliability and repeatability.


Tremetrics Oscar 6 Electro-Acoustic Ear

a7Always insures the validity of your hearing conservation program by checking audiometer test accuracy daily. With the portable OSCAR 6 Electro-Acoustic Ear, the operator simply places the earphones on the color-coded couplers and conducts a hearing test. The resulting data provides a permanent, legally acceptable running log to establish that the audiometer is “in calibration.” The reliable OSCAR works equally well with manual, automatic and microprocessor audiometers.When used with Tremetrics audiometers, the unit performs an accelerated test which speeds up compliance with the OSHA required daily functional check.
