Wireless Spirometer

Product Code: PS-3234


PASCO’s new Wireless Spirometer Sensor makes it safe and easy for students to collect respiratory measurements, including flow rate, pressure, and lung volume. Ideal for studies in health and human physiology, the Wireless Spirometer Sensor streamlines experiments by providing students with real-time data, interactive graphs, and analysis tools on virtually any device. The disposable mouthpieces are designed for use with a single student and feature exchangeable filters that protect the sensor from particulates to ensure long-term hygienic use. Additional mouthpieces and pre-filters are available in convenient packs of ten.

The PASCO Wireless Spirometer allows students to determine the volume of gas that passes through a tube during expiration, their total lung volume, and the factors that can affect it. Students can also estimate the amount of oxygen in their bloodstreams and the overall oxygen efficiency of their lungs by integrating data from a PASCO Wireless Oxygen or CO2 Sensor. Use lung efficiency with total breath volume allows students to estimate calories burned for activities. Excellent for Biology, human physiology and health classes.

Educational Use Only: This is not a medical device. PASCO products are designed for educational use only and should not be used in any apparatus involved with life support, medical testing, patient diagnosis, or industrial control/testing systems.


  • Once charged, use all day for several classes
  • Wireless sensor untethers students to explore breath rates and oxygen use around campus
  • Wireless sensor blinks green at start after calibration and is ready to draw air through the sensor
  • Easy to change mouthpiece and filter assure accurate airflow measurement while greatly reducing any chance of cross contamination


  • Determine rates of inhalation vs exhalation for lung elasticity
  • Determine tidal volume of lungs
  • Determine average per breath volume of lungs
  • Use per breath volume with O2 exchange efficiency (using separate O2 gas sensor) to determine calorie consumption
