Interacoustics AT235 "H" automatic middle ear analyzer (tympanometer) with 678/800/1000 Hz tympanometry, ETF3 and reflex latency

Interacoustics AT235 "H" – automatic middle ear analyzer with extended (H) license

The Interacoustics AT235 automatic middle ear analyzer (tympanometer) is ideal for both diagnostic and clinical evaluations. In addition to tympanometry and reflex testing it includes pure tone audiometry (screening) and the Modified Hughson–Westlake audiometry test, combining middle ear assessment and basic audiometry in one device.

The 10" adjustable colour display shows several test results on the same screen. The unit can be used on the desk or wall-mounted, and test data can be transferred to a PC.
