Military screening audiometer
The definitive military screening audiometer designed to meet all current and future audiometric screening requirements. Equipped with automated processes and in-built capacity to meet additional testing needs, the CA850/4A supports screening programmes in the most effective manner.
Comprehensive testing
The device includes automatic (computer / Békésy) and manual operation options to measure and assess hearing thresholds in accordance with safety critical hearing standards. With configurable options the test can be customised to the users’ specific requirements, ensuring accurate and efficient testing. Designed to connect directly to a PC (automatic testing) or as a stand-alone manual audiometer (manual mode).

Key benefits
- Pre-qualify leads to ensure quality referrals
- Grow & diversify your business through increased testing
- Save time and resources without the need for an audiologist
- Easily assess hearing as part of a holistic health check
- Deliver a hearing screening service with no additional software, costs, or subscription fees
Configuration options
The CA850/4A works with all Windows compatible computer / tablet systems. Supplied without or without a dedicated computer, the CA850/4A can integrate with required IT configurations.
Alternatively, the CA850/4A can be supplied with a laptop allowing for complete mobile testing with features that can be restricted according to user requirements.
The device also has built in configuration to be upgraded to a Functional Hearing Assessment System (FHAS) with Speech-in-Noise (SiN) testing.
Cost savings
The CA850/4A reduces the need for additional hardware requirements such as printers, toners / ink cartridges and dedicated paper, making for a paperless audiometry workflow.

Results processing
The CA850/4A offers automated workflow management from patient information, testing and results calculations along with referral guidance. Test results are categorised according to PULHHEEMS and HSE standards.
Standalone
For users who don’t wish to maintain two databases or would like to maintain a standalone system, the CA850/4A software can operate without a database.
Test results are automatically categorised and can be processed (Printed / PDF).
With database
For those who wish to manage test results in a separate database as part of a Hearing Conservation Programme, users can use the supplied Amplivox database solution.
The software allows for results processing, comparisons, trending and automated recalls.
EMR Connectivity
The device can be integrated with many leading Electronic Medical Record (EMR) systems including Cority, Eopas, G2 and Cohort to provide a seamless audiometric test function.
The system can also be configurable to bespoke EMR applications typically used within the MoD.
