British CITY car oxygen sensor AO2, the AO2 PTB-18.10 oxygen sensor used on the oxygen index tester is a consumable. When it comes into contact with the air, a chemical reaction occurs. Generally, the validity period of the oxygen sensor is one year. The package must be airtight, usually in a sealed plastic package filled with nitrogen, and the best storage temperature is between 0°C and 20°C.
AO2 PTB-18.10 is used in various instruments related to oxygen testing, such as: vehicle exhaust gas detection instrument, exhaust gas environmental protection detection instrument, oxygen index test instrument.

The output of the AO2 sensor varies with temperature, but gradually integrates thermistors to compensate for these changes. A 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, and when it comes into contact with air, a chemical reaction begins.
Shelf life:
In general, the validity period for use is one year.
The original packaging of the oxygen sensor must be sealed, usually in a sealed plastic package filled with nitrogen.
The best storage temperature is between 0°C and 20°C.
