AZ26 clinical impedance audiometer is built to meet the demands of clinics and hearing specialists who require a comprehensive middle ear analysis instrument. Tests include automatic and manual control tympanometry with selectable pressure ranges and pum speeds, acoustic reflex tests with up to 16 recordings per ear, reflex decay with 10 or 30 seconds presentation, and a high resolution latency test with automatic latency calculation. All tests may be performed automatically or manually. Eustachian Tube Function may be determined on patients with normal or perforated eardrums.

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. It is also lightweight, which facilitates portable use with the optional dedicated hard walled case.
