A great overview

The 10” adjustable display provides a great overview of the measurements where several test results can be seen on the same screen. The image is sharp and clear. The screen can be tipped and adjusted to avoid light re ection on the screen.
The built-in HDMI output makes it possible to show the screen on a projector or TV. This may be relevant in counseling sessions to help the client get a better understanding of the test results. It is also ideal for educational purposes, as students can easily follow the test results when displayed on a larger screen.
Few dedicated buttons on the AT235 make it easy to navigate between various functions. Function buttons with changing help texts on the screen guide you to navigate efficiently.

User friendliness brought to the next level

Dedicated probe systems

You can choose to have both probe systems included with your AT235. It is quick and easy to change between the two probe systems.
The diagnostic probe is hand-held and ideal for quick tympanograms and a screening reflex.
The clinical probe is ideal for more lengthy assessments where stability is important and any interference from extraneous noise should be avoided.

Customizable protocols to meet specific client types

You can create a simple screening procedure and a more in-depth evaluation. Avoid wasting time with different client types as each test protocol can have separate test limits to meet the need of a specific client types.
