The CA850 Series 5 audiometer is the definitive industrial screening audiometer. It is designed to meet all current and future audiometric screening requirements and will automatically measure, record and categorise hearing levels in the most effective manner possible.

Test type

Three test methods including the self recording/bekesy type test ensure that the appropriate test type can be used to fulfil an audiometric screening program.

Ease of use

From switch-on, three key presses and a test is performed. The audiogram and related test information are displayed on the large integral LCD for review and to ensure no inconsistencies. Results analysis is automatically performed in accordance with the HSE categorisation procedures and innovative features can identify ‘at risk’ personnel within the internal database.

Test recording

Utilising USB technology, the CA850 Series 5 offers comprehensive results options. Archive quality prints, a password protected internal database (up to 2000 complete records) and a bi-directional PC link facilitate all requirements. The instrument can also be supplied with Amplivox Audibase PC software for statistical analysis requirements.

The ideal audiometer

Compact, lightweight and extremely reliable by virtue of the fact that there are no moving parts, it is the ideal audiometer for both desktop and mobile screening requirements.

Database compatibility

The Amplivox CA850 Series 5 is compatible with all leading occupational health databases to provide electronic data storage and statistical analysis benefits. The audiometer can interface to OPAS and E-OPAS, Cohort and Medgate OH databases.
