Otowave 202/202H

STANDARD HANDHELD DIAGNOSTIC TYMPANOMETER

  • Standard Handheld Diagnostic Tympanometer With High Frequency Option 

     

  • The Standard Otowave 202 provides 226 Hz probe tone impedance measurements together with a user programmable range of both ipsi and contra lateral reflex test measurements at 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz.

    The Otowave 202-H 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.

    • Auto pass/refer evaluation
    • User selectable measurement speeds
    • Internal memory, connection to portable printer and/or PC

Product Specs

  • 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

    Probe Tone Levels: 226 Hz ± 2%, 85 dB SPL ± 2 dB; 1000Hz ± 2%, 79 dB SPL ± 2 dB (202-H only) over ear canal volume range

    Pressure Levels: +200 daPa to – 400 daPa, ± 10 daPa or ± 10% (whichever is larger) over range 0.1 ml to 6 ml

  • Ear Volume Measurement Range: 226 Hz: 0.2 ml to 6 ml; 1000 Hz: 0.1 ml to 6 ml ± 0,1 ml or ± 5% (whichever is larger)
