The output of the sensor changes with temperature, but the thermistor is gradually integrated to compensate compatible with these changes. The thermistor is used to give the a very stable output over a wide temperature range. The .10 oxygen sensor used in the oxygen index meter is a consumable item. When it comes into contact with air, a chemical reaction begins.
