GSI 39

The GSI 39 Auto Tymp provides a flexible screening product for tympanometry, acoustic reflex measurements and audiometry to meet your testing needs today and in the future. It is available in 5 different versions. Choose the features needed today and upgrade easily to the additional features as your needs grow in the future.

•    Tympanometry – 226 Hz:
            Ear Canal Volume (ECV)
            Compliance Peak (cm3)
            Pressure at peak of the tymp (daPa)
            Gradient (GR) in daPa (width of the tymp)

•    Tympanometry – 1,000 Hz:
        *    Admittance at +200 daPa (C1)
        *    Admittance at tymp peak (mmhos)
        *    Pressure at tymp peak (daPa)
•    Reflex results may be displayed and printed as:
        *    Reflex tracings and dB HL values
        *    dB HL values only
        *    Yes/No response
•    Maximum of 12 test results can be stored
•    Built- in printer available in all versions

Available configurations:
