Amplivox CA850 Series 5 Audiometer

Suitable for use in occupational health or general practice, the CA850 Series 5 Audiometer from Amplivox is ideal for mass screening programmes.

Designed to meet all current and future audiometric screening requirements, the CA850 automatically measures, records and categorises results in an effective manner to improve workflows.

The unit supports three test methods, including self-recording/Bekesy type tests ensuring the correct test type can be used to fulfil any test requirements.  Results are categorised according to HSE-approved methods, allowing at-risk personnel to be easily identified.

The large, integral LCD display shows audiograms and test information allowing users to check information on the unit, reducing errors and improving care.  Up to 2,000 complete records can be stored on the audiometer in a password-protected database. 

The audiometer can be connected to a printer or PC using a standard USB cable allowing data to be recorded in hard copy or attached to an electronic patient record.

The CA850 is supplied complete with audiometric headset, patient response switch, 250 audiogram cards, mains adapter and carrying case.
