Measurement principle
O2 sensor based on ZrO2(zirconium oxide)
When voltage is applied to the sensor element, oxygen concentration dependent current will be generated.
Infrared sensor
Diatomic molecule absorbes specific wavelength infrared light and its absorbance is propotional to concentration.
Using two wavelengths improves reliability by comparing the absorbance of the specified wavelength with that of all range.
