NOTICE
Hydrogen sulfide and ammonia shorten the operating life of the sensor.
‣
Do not use the sensor in applications where it is exposed to hydrogen sulfide or
ammonia vapors.
Cross-sensitivity
COS22-*1/3
Molecular hydrogen causes false low readings and can, in a worst-case scenario, result in
total failure of the sensor.
