Spirometer Sensor   Home / SmartQ Sensors  

A spirometer that is portable, small, compact and needs no special gases or water. 

The hand held unit measures air flow by pressure difference. A utility in the Easysense software converts flow data to volume data. You can measure lung capacities, flow volume loops and lung ventilation efficiency.

Teaching applications:
  • 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

  • Comes complete with a starter pack of 4 filters, circular mouth guard and nose clip.
  • Filters are anti bacterial and anti viral. Replaced after use.
  • One filter is left fixed as the pressure divider.
  • Not suitable for Diagnostic or medical use. For educational / demonstration use only

Teaching Materials

Lung capacities (spirometer) (Biology (14-18) eBook)
Activity to measure, record and analyse breathing volumes. Uses an airflow spirometer - no need for gallons of water.

Lung function (spirometer) (Biology (14-18) eBook)
Demonstration of FEV1 and associated values. FEV values are used to determine lung function in fitness training or diagnosis of lung disease. Unlikeley to be able to do with traditional water filled spirometers.

Flow volume loop (spirometer) (Biology (14-18) eBook)
The flow volume loop is used in diagnosis and monitoring of asthma and pulmonary obstruction. A good demonstration of medical technology.
