Otowave 302/302+

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.

Features:

• Compact design with a graphic LCD display
• 226Hz probe tone or 1000Hz probe tone (302+) with admittance, susceptance and conductance measurements (YBG)
• Live tymp display - measurements shown in real time
• Ipsilateral and contralateral reflex frequencies (0.5, 1000, 2000, & 4000Hz)
• Auto pass/refer evaluation (ear canal volume)
• Fast and accurate impedance measurements
• Intuitive use/ real time display
• Optimized, user-selectable measurement speeds
• Six user-configured test protocols (302+)
• Internal memory, PC connectivity and optional portable printer

Analysis Performed: Compliance peak level (in ml), Ear canal volume (ECV) at 200 daPa or -400 daPa, Ipsilateral reflex or ± 10 daPa or ± 10% (whichever is larger) over range 0.1 ml to 6 ml
