A spirometer is an apparatus for measuring the volume of air inspired and expired by the lungs. A spirometer measures ventilation, the movement of air into and out of the lungs. The spirogram will identify two different types of abnormal ventilation patterns, obstructive and restrictive. There are various types of spirometers which use a number of different methods for measurement (pressure transducers, ultrasonic, water gauge).

No Calibration Needed
No messy setup or teardown
Compact, easy to use and store
Measurements of lung functions can vary dramatically from person to person. You can easily demonstrate and measure these differences in your classroom with this accurate, handheld, dry gas meter. It measures vital capacity, tidal volume, and expiratory reserve volume. Students can then calculate inspiratory reserve volume and inspiratory capacity from these values. The gauge is calibrated to 7L in 100-cc increments. Just reset the needle after each reading by rotaing the dial. Includes 50 reusable mouthpieces, 7/16" D.
