Interacoustics AT235 and AT235h

The AT235 is an automatic impedance audiometer well suited for all screening or diagnostic applications. The entire standard battery of impedance tests is available, including a choice of manual or automatic reflex testing, ipsi- and contralateral reflex decay, ETF test as well as pure tone audiometry. Two probe systms are available - a small and lightweight all new clinical probe or a standard handheld pencil type probe design well suited for screening or typical diagnostic work. The completely new DSP board developed for this unit results in an unprecedented flexibility in use and a high test speed. The AT235h includes all the functions of the AT235, and additionally features tympanometric screening, using either 678Hz, 800Hz or 1000Hz as probe tone frequency.

Interacoustics A220

The cost effective and space saving combination of impedance bridge and audiometer makes the AA220 well suited for any stationary or portable application, where diagnostic testing of AC, BC, tympanometry and reflexes are performed. The time saving automatic test function combined with the RS232 computer interface, makes the AA220 ideal for modern healthcare environments. The AA220 is available with or without integrated high speed thermal printer.

Madsen ZODIAC-901

ZODIAC 901 is a remarkably versatile middle-ear analyzer from Otometrics, Denmark, the innovators who in 1961 introduced the world's first electro-acoustic impedance bridge, the ZO 61. Since then, Madsen have produced and distributed over 12,000 impedance units worldwide, testimony to the high quality and unrivalled reliability of our products as well as to the widespread use of acoustic impedance measurements in audiological diagnostics. Much research and development has been done since the early days of impedance measurement, culminating in ZODIAC 901, the most advanced impedance instrument in the world today.

Madsen OTOflex

There are three secrets behind this remarkable concept. First, our innovative new probe can be used for any size of ear, from premature babies to adults. Second, full integration means that in addition to manual testing (just use the scroll wheel to switch to a new test), you can create automatic sequences that perform an entire battery of sophisticated tests at the touch of a button.

You can also overlay multiple tympanograms for pre-/ post-treatment comparison. Finally, thanks to Bluetooth wireless communication and an all-day battery, OTOflex is free to move where you do, linking seamlessly to our complete otodiagnostics software suite whenever you are near your PC (the OTOdiagnostics Suite is supplied as standard with OTOflex 100).

Maico MI-34

The MA 34 performs automatic impedance measurements for screening or in-depth middle-ear evaluations quickly and easily. In just seconds the results are displayed on the LCD screen and be printed out after each test automatically. Special diagnostic testing for IPSI and CONTRA reflexes, reflex decay and Eustachian tube functions are included in this powerful and versatile instrument.
