The Spirometer measures air flow by pressure drop across a reference flow resistance while the user breathes. It is portable, small, compact and needs no special gases or water.

The Spirometer Sensor comes complete with a starter pack of 4 filters, a circular mouth guard and nose clip. One filter is left fixed as a pressure divider, the other three are for use by test subjects. For educational / demonstration use. Not suitable as a diagnostic tool or for medical use.

  • Breathing patterns before, during and after exercise
  • Lung capacities
  • Lung efficiencies FVC, FEV1 and FEV6, MVV
  • Flow volume curves
  • Slow Vital capacity (SVC): The user should breathe normally 3 times and then inhale to the maximum extent of total lung capacity and then expire to the maximum extent
  • Maximal voluntary ventilation (MVV): The user should breathe as deeply and as rapidly as possible over a period of 6 to 12 seconds
