Product Description


The SmartQ ±10kPa Differential Gas Pressure sensor and Breathing Rate belt are used together to measure the expansion and contraction of a person’s chest while they breathe. 

The Breathing Rate belt is wrapped around a person’s chest and inflated. As you breathe the pressure of the air trapped in the belt varies. A tube connects to the pressure sensor that measures the changes in pressure as you breathe and the chest capacity changes. 


Teaching applications:
  • Measuring breathing rates
  • Changes of the body in exercise
