Basic Diagnostic Audiometer Bell Plus

The Bell Plus audiometer is an advanced and versatile device designed to perform precise and quick hearing tests, both through air and bone conduction.

The Bell Plus is one of the two available configurations of the Bell audiometer, the other being the Bell Basic model. While the Basic model is limited to air conduction, the Bell Plus includes both air and bone conduction, making it ideal for a wider range of clinical and occupational medicine applications.

The Bell Plus incorporates Inventis Hy-Tech technology, allowing the user to decide whether to operate it traditionally as a standalone audiometer or control it through a computer. This flexibility in the operating mode makes it very adaptable to different clinical environments.

The Bell Plus audiometer easily connects to a computer via a USB port, without the need for additional drivers. This allows for the direct transfer of test results to Maestro or Noah databases, and offers a live display function for a broad view of the ongoing exam on the computer screen.

It has a color graphic display that shows the audiogram in real time, facilitating the interpretation of results during the exam.

The Bell Plus is designed to be easy to use and portable, making it ideal for private clinics, multi-specialist clinics, and occupational medicine applications. Its compact size (32 x 32 x 9 cm) and moderate weight (1.8 kg) facilitate its transport and storage.

The audiometer has an internal memory capable of storing up to 100 patients with air and bone conduction thresholds, allowing efficient management of exam data.

The audiometer's calibration is valid for 12 months, and all parameters can be adjusted through the device's software, ensuring the accuracy and reliability of the results.
