Speed and simplicity
Maico combines the speed and simplicity of an impedance screener with the added functions of reflexes and reflex decay tests usually found only in more expensive diagnostic instruments.
Automatic test results
The MA 34 performs automatic impedance measurements for screening or in-depth middle-ear evaluations quickly and easily. In just seconds the results are displayed on the LCD screen and be printed out after each test automatically. Special diagnostic testing for IPSI and CONTRA reflexes, reflex decay and Eustachian tube functions are included in this powerful and versatile instrument.
Guaranteed to meet your demands
The Maico MI 34 is a lightweight, easy to use impedance screener/diagnostic instrument that will provide reliable, accurate results for years to come.
