Basic diagnostic


Bell is a screening/diagnostic audiometer, capable of performing fast and accurate air and bone threshold examinations.
Simple operation, a user-friendly interface and easy portability make Bell the ideal instrument for private clinics, multi-specialist clinics and occupational medicine applications.

It is available in two configurations to suit different user needs:

  • Basic (AC only)
  • Plus (AC & BC)

Bell features Inventis Hy-Tech: it is possible to decide whether to operate it in the traditional way (stand-alone mode) or control it through the computer.

Simply connect Bell to a USB port on your computer (no drivers needed), and you can transfer exam results into Maestro or Noah database. With the live view feature, you can have a wide view of the examination in progress on the computer display.
