ASRA Curve Screening Audiometer

The Asra Curve performs air conduction screening, backed up with additional software to perform tasks such as annual statistics and recall lists. Designed to build on the reputation of the Asra Classic, the Asra Curve offers many of the same unique features but combines the latest electronics with a smaller product to better fit current healthcare environments.

Unique to the Curve is the ability to quickly swap headsets (and calibration) and to easily move the unit between PC’s. It comes complete with a noise reduction headset, all cables, testing and batch utility analysis software, and a manufacturer’s calibration certificate.

The ASRA Curve Audiometer provides a number of benefits to the user:

  • Employs modern electronics, coupled with continually developing/updating software, to provide a unique range of facilities. These are delivered in a user-friendly package, for progressive occupational health professionals to use.
  • Ability to have more than one headset calibrated to the instrument ensuring minimal downtime in the event of a headset malfunction.
  • Full support is included with UK deliveries at no extra cost.
  • We are also able to supply a follow on comprehensive warranty and support package. This ensures customers continue to enjoy the benefits the ASRA audiometer has to offer, for many years to come
