Otowave 202 & 202-H

Handheld diagnostic tympanometers

Handheld diagnostic tympanometers that provide fast and accurate middle ear measurements in all age groups including neonates. The ideal choice for audiology, ENT and hearing care professionals who require a portable tympanometer for both mobile and clinical test settings.

The Otowave 202 and 202-H also offer a wide range of test functionality to ensure testing requirements can not only be met, but exceeded.

Designed for small ears

Conducting middle ear measurements for neonates and children is fast and accurate, with diagnostic information displayed during and after the automatic test. Test settings can be defined according to the requirements of the patient.

With a probe specifically designed for small ear canals, middle ear measurements for neonates and children can be conducted with speed and accuracy. Diagnostic information is displayed via the display during and after the user defined measurement routine.


  • Designed for handheld and desktop use
  • Mains and battery power functionality
  • 226Hz probe tone
  • Optional 1kHz probe tone (202-H option) with admittance, susceptance and conductance measurements (YBG)
  • Live display
  • Enhanced Ipsilateral and contralateral reflex frequencies (0.5, 1, 2 and 4kHz)
  • Enhanced mode reflex test
  • Auto pass/refer evaluation
  • Fully customisable test protocol
  • User selectable measurement speeds
  • Internal memory, connection to portable printer and/or PC

Data management

With the added benefit of an internal memory function, test results can be printed immediately or saved for future processing using the supplied Amplisuite software. The tympanometer also offers single-click integration to third-party Electronic Medical Record (EMR) systems such as Auditbase, NOAH and OtoAccess®. This enables the seamless transfer of results and data for exceptional workflow efficiency.



Weighing only 430g (with batteries), the simple design allows for complete portability. Powered by AA batteries or via mains power, the Otowave 202 is ideal for mobile use or in a static clinical setting where space is at a premium.

  • Comprehensive testing

    The Otowave 202 provides 226Hz probe tone impedance measurements while the 202-H features a more comprehensive range of diagnostic test functions including user defined 226Hz and 1000Hz probe tone impedance measurements. 

    The high frequency testing option of 1000Hz tympanometry makes this device ideal for assessing new-borns. When using the Otowave 202-H option in 1000 Hz probe tone mode, users can select a preferred display by pressing the probe function key to switch between the following modes:

    • Scalar mode: a traditional admittance tympanogram, as above (Y only compensation)
    • Vector mode: a tympanogram displaying B-G compensation
    • Component mode: the separate admittance (Y), susceptance (B) and conductance (G) measurements are displayed for clinical review
    • User-defined ipsi and contralateral reflex test measurements can be added to the test sequence to ensure a comprehensive test routine. This user programmable acoustic reflex function includes reflex frequency selection, levels and sensitivity

    Both devices offer a user programmable range of both ipsi and contralateral reflex test measurements at 500Hz, 1kHz, 2kHz and 4kHz.
