Basic Bell Diagnostic Audiometer

The Bell Basic audiometer is characterized by its simple operation and easy-to-use interface, making it ideal for private clinics, multi-specialist clinics, and occupational medicine applications.
Its easy portability and compact design make it a versatile and practical instrument.

The Bell Basic is specifically configured for air conduction, distinguishing it from the Bell Plus model, which also includes bone conduction.

The Bell Basic audiometer incorporates Inventis Hy-Tech technology, which allows it to be operated in two ways: in traditional standalone mode or controlled through a computer. This versatility increases its usefulness in different clinical settings.

It can be connected to a computer via USB without the need for drivers, allowing test results to be transferred to Maestro or Noah databases. The live visualization function allows a wide view of the ongoing exam on the computer screen.
