Fangrui Product Details 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 Item. When It Comes Into Contact With Air, A Chemical Reaction Begins.
