Great test result overview

The 10" adjustable display provides a great overview of the measurements where you can see several test results on the same screen. You can tip and adjust the screen to avoid light reflection. The HDMI output also allows you to show test results on large screens, which can be useful for client counseling and in educational settings.

Diagnostic and clinical probe systems

AA222 comes with two different probes, each ideal in certain clinical situations.

The diagnostic probe is handheld and ideal for quick tympanograms and acoustic reflex screening. The clinical probe is ideal for more lengthy assessments where stability is important and any interference from extraneous noise should be avoided.

You can choose to have both probe systems included with your AA222. It is quick and easy to change between the two probe systems. You can place the clinical probe shoulder box on your client by using the optional headband, clips, or key hanger.

Probe status is displayed on the probe shoulder box for both probe systems. This enables you to keep your focus on the client. Both probe types only need a simple button press to alternate between ears.
