An elegant and tidy audiometry workstation underlines the demand for high-quality functional diagnostics.
The KA450 is a high-quality 2-channel clinical audiometer and requires neither a PC nor a network connection for operation.

Nevertheless, it is fully integrated into our audioApp software. It can then be operated on the device and via the software as required.

Classic audiogram forms can also be filled out very easily with the optional LED matrix.

The Freiburg speech test is stored on a memory card in the device and saves you the tedious work of using a CD player.
