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.
