The Microtymp
(Welch Allyn).

Description : Tympanometry provides an objective measurement of middle ear function by measuring sound reflected from the tympanic membrane while the pressure in the external ear canal is changed from a positive pressure of 200 dPa through normal atmospheric pressure to a negative pressure of ‑ 300 dPa.
 
The MicroTymp is a small, hand‑held portable automatic tympanometer (impedance audiometer) which is shaped like an otoscope, and which provides an objective measurement of middle ear function in 3 seconds and displays the results on a liquid crystal display.

The graphic display from each ear can be stored in memory and when the test is completed a permanent hard copy of the test can be printed out for the records.
