Diagnosing chronic otitis media is often a difficult task. But the delivery of sound and air pressure to the ear, precisely measured by advanced microelectronic components, brings otitis media into sharp focus. Welch Allyn's MicroTymp 2 tympanometry instrument produces an accurate, objective measurement of middle ear status. It also helps detect perforated tympanic membrane, patent tympanostomy tube, ossicular disruption, tympanosclerosis and cholesteatoma. Takes only one second to test and five seconds to print out the results. MicroTymp 2 is lightweight and hand-held for complete portability. Color-coded tips come in four sizes to fit any ear size.
