Remark
Depending on gas type and gas concentration - specific operating conditions of the gas sensor
have to be respected.
Important remarks
Any contamination of the sensor must be avoided. The application, transport and storage environment has to be free of any contaminations, particularly protected against chemical substances, e.g. silicones.
In particular directly contact with substances containing, silicones, sulfurous substances or nondesorbing inorganic components or contaminations (e.g. smoke, fumes, oils, greases or evaporating liquids) may cause damaging the sensor or to changes in the sensor resistance and/or in
the sensor characteristics.
