Sanitary FVC Tester / FVC Tester

Sanitary FVC Tester

We use the working principle of Wheatstone bridge to design a sanitary public FVC tester which doesn't have the air-blowing-cup structure , avoiding uses directly contacting with the public FVC tester .
The machine has Two bridge which controls the heating power of heating sensor .So that the heat sensor and the reference temperature sensor can maintain a constant temperature. According to the variation of heating power, using the mathematical formula △ t = ts-ta = constant, the system can calculate the volume of gas. and the volume is an individual’s lung’s capacity.
