Amplivox Otowave 302+ Desktop Tympanometer with PC connectivity  8522197 (No printer)


The Amplivox 302+ tympanometer with Probe tone impedance measurements at 226Hz and 1000Hz; focuses on supporting time management, whilst providing accurate middle ear measurements. It includes a customisable, six profile selection structure to save you time changing test settings. 

Three are default profiles for adult, child and neonate, and a further three are blank profiles to personally adjust.



  • Large digital display for fast, accurate impedance measurements 
  • 226Hz probe tone and 1kHz probe tone with admittance, susceptance and conductance measurements (YBG)
  • Measurements shown in real time
  • Ipsilateral and contralateral reflex frequencies (0.5, 1, 2 & 4kHz)
  • Enhanced mode reflex test
  • Auto pass/refer evaluation
  • Six fully customisable test protocols
  • User-selectable measurement speeds
  • Internal memory, connection to thermal printer and/or PC.



The Otowave 302+ features extended functions including user defined:
Probe tone impedance measurements at 226Hz and 1000Hz (scalar,
vector and component measurements; admittance (Y),
susceptance (B), conductance (G))
Range of ipsilateral and contralateral reflex test measurements at
500Hz, 1kHz, 2kHz and 4kHz
Six user configurable test profiles designed to standardise test
sessions and reduce test times. This includes three profiles for adult,
child and neonate, plus three customisable profiles based upon
your needs.



Three pre-set profiles and three customisable profiles, the 302+ can easily be adjusted to suit your requirements.

This includes adjustable test settings for the following:

  • Probe tone (226 / 1000Hz)
  • Sweep speeds
  • Ipsilateral reflex frequencies
  • Contralateral reflex frequencies
  • Fixed test level or threshold test
  • Pass/Refer criteria

Test settings can easily be changed depending on your preference or test subject in question. The Otowave 302 offers you to easily define the following test settings in no time.


The Amplivox Otowave 302 Tympanometer intuitive to use with clear on-screen information, which can be easily seen from a wide range of viewing positions. Results can be saved within internal memory with a patient identifier, printed via the optional portable thermal printer, transferred to a PC using the supplied Amplivox Tymp View application for paper print and electronic document requirements, transferred to the NOAH database using the supplied Amplivox NOAH Impedance module.

All tympanometers include free to use ampli Suite. This very easy to use software allows you to easily transfer results, analyse, add patient data, categorise, print and store.

Amplivox also includes the NOAH connection module and many other Electronic Medical Record (EMR) providers have integrated this product to their system for easy data management.
