Rhinomanometer and spirometer: PDD-301/r

The device insures the measurement of nasal resistance and the basic pulmonary function testing.
It is inevitable in objective diagnose of rhinitis and in the ENT practice

The PinkFlow* flow-meter and the rhinomanometer fully complies with the specifications and requirements of the Standardization of Lung Function Testing ATS/ERS Task force (European Respiratory Journal 2005)

Connecting to a laptop PC provides full portability in battery mode as well
