The MAICO Impedance Meter MI 24 has an adjustable probe with an integrated left and right selection button. The ergonomically designed device is comfortable and easy to use, providing a fast, automatic test at just 3 seconds for one tympanogram. It features an LCD screen which immediately displays tympanogram and test results. The real time reflex is displayed graphically. The device has a memory capability that can store the test results for both ears; it produces a fast and virtually silent print-out of these results. An ipsi and contralateral reflex test can be performed with 4 frequencies. The menu is adaptable to individual needs.
