Standard Desktop Diagnostic Tympanometer

Schedule demo

  • Desktop Diagnostic Tympanometer With Optional Patient Profile Programming

  • The Otowave 302 and 302+ tympanometers offer clinicians a wide range of testing options for all ages. 

    The 302 provides 226 Hz probe tone impedance measurements and a user programmable range of ipsi and contralateral reflex test measurements at 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz.

    The 302+ option features a comprehensive range of test functions including user defined 226 Hz and 1000 Hz probe tone impedance measurements and a user programmable range of both ipsi and contra lateral reflex test measurements at 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz

    In addition to these features the 302+ also has 6 additional programmable patient profiles, allowing for faster testing.
