The CA850 Series 4 audiometer is the definitive industrial sceening 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 Bekesy 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 4 offers comprehensive
results options. Archive quality prints, an internal database
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.
