The output of the AO2 sensor changes with temperature, but the thermistor is gradually integrated to compensate for these changes. The thermistor is used to give the AO2 a very stable output over a wide temperature range.

The AO2 PTB-18.10 oxygen sensor used in the oxygen index meter is a consumable. When it comes into contact with air, a chemical reaction starts.
