Student Spirometer

This spirometer offers so little resistance to the movement of air to and from the subject’s lungs that it does not affect the subject’s respiratory movements.

  • 9-liter capacity
  • 30 mm ID airways result in nearly 50% greater cross-sectional area than traditional 22 mm bore tubing
  • A one-way air valve with mica disc construction minimizes resistance
  • Counterweight minimizes weight of gas holder
  • For use with the Transducer Interface and the Student Oscillograph

As a teaching device, this spirometer has a number of important extra features.
