Maico Diagnostics MI 34 Middle Ear Analyzer with Reflexes and Reflex Decay Tympanometer Perform automatic impedance measurements for middle ear evaluations. The new high frequency option is ideal for pediatric and neonatal screening programs.
Maico combines the speed and simplicity of an impedance screener with the added functions of reflexes and reflex decay tests that are usually found only on more expensive diagnostics equipment.
LCD type graphical display shows graph of tympanogram, peak compliance, peak pressure, canal volume, gradient, reflex, graph and conclusion. |
