Respiratory rate sensor
1,compare and measure the respiratory rates
2,high precision school biology laboratory equipment

1,Range: -300L/min ~ + 300L/min
2,Resolution: 0.05L/min

3,Application: The Respiratory rate sensor is widely used in educational experiments, it can compare the respiratory rates before and after exercise, can display the air pressure change curve during the respiratory course and calculate the relation between respiratory rate and heart rate.

4, Direction:  closely connect the interface of the chest strap with the sensor hose, tie tightly with the air pocket in the chest strap against the lung and wind the inflating ball valve to inflate the air pocket. Observe the wave curve on the software and stop blowing if there is up and down variation of the curve displayedin the middle of the screen.
