The oxygen sensor AO2 for automobiles, used in the oxygen index measuring instrument AO2 PTB-18.10, is a consumable. When it comes into contact with air, it undergoes a chemical reaction and is generally valid for one year. The packaging of the oxygen sensor must be sealed, usually in a sealed plastic packaging filled with nitrogen gas. The optimal storage temperature is between 0 ° C and 20 ° C.
AO2 PTB-18.10 is used in various instruments related to oxygen testing, such as motor vehicle exhaust detection instruments, exhaust environmental protection detection instruments, and oxygen index testing instruments.

The output of AO2 sensors varies with temperature, but gradually incorporates thermistors to compensate for these changes. Thermistors are used to provide very stable output to AO2 over a wide temperature range.
The AO2 PTB-18.10 oxygen sensor used on the oxygen index analyzer is a consumable that undergoes a chemical reaction upon contact with air.
quality guarantee period
Generally, the validity period for use is one year.
The original packaging of the oxygen sensor must be sealed, usually in a sealed plastic packaging filled with nitrogen gas.
The optimal storage temperature is between 0 ° C and 20 ° C.
