Auditory potentials ABR BERA 4000

ABR BERA 4000 is an audiometer for auditory evoked potentials of the brainstem. BERA 4000 is a very advanced device giving the results in real time.

BERA 4000 uses the latest processors, so making changes in diagnostic requirements can be achieved by simply updating to the newest version of the software. This software is very easy to use. In addition, it is possible to create custom measurement programs and an EXPERT-MODE allows you to create and change settings during the measurement sessions, so you can tailor the session to the patient’s needs and situation. During the test, you can measure 16 curves and save them in the cache. Analysis / evaluation of results can be made at a later time. Display of the curves and device control is done using a PC / Laptop. Software is available in many languages. BERA 4000 is available in standard or modern antibacterial Blue Line housing.
