The NV2 Rhinospirometer is a stand-alone device which allows the measurement of portioning of airflow between two nasal passages and provides a Nasal Partitioning Ratio (NPR).

Acoustic Rhinometers allow a very rapid non invasive examination of the nasal cavity using a sound pulse technique. Acoustic Rhinometry was developed originally during a joint collaborative project between the Universities of Aarhus (Denmark) and Boston (USA). GM Instruments was invited to commercialise the system, and has been actively working with interested parties to update and improve the measurement since then. A Rhinometer quantifies nasal structure and measures this in terms of absolute levels and the effect of interventions, thus allowing % change to be recorded.

Designed to be a lightweight, small but robust screening instrument, ideal for Occupational Health Nurses or Technicians on the move, it provides the testing capability required for workplace industrial screening. The recorded files are generated in the same file format as the ASRA Classic and ASRA Curve audiometers and as such can be interchanged for storage and/or comparison purposes. Printouts are produced in full A4 size for ease of assessment, and long term stability and can be saved in pdf format. Osicus offers a unique additional feature, as a comparison between current and previous audiogram for an individual can be generated to predict potential future hearing degradation unless the rate of loss is reduced, normally by a change in exposure.

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.
