Measuring principleWhen be normally breathing, the gas passed through the flow sensor. On both sides of the screen of the sensor will produce different pressure. The pressure is detected by the sensor, which is converted to electrical signals. After the signal amplification, AD converter sampling, the pressure is converted to digital signal into the computer system.Through digital signal processing and analyzing technology, computer system reproduces the breathing waves that are displayed on the LCD together with analyzed results. In the end thebuilt-in printer printsout the analysis results.Single use filter
