Precautions

• Remove the protective film before use
• Avoid volatile silicone compound vapours (silicone adhesives and rubber, hair gel), high concentrations of corrosive gases (H2S, SOx, Cl2, HCl), contamination by alkalis and halogens
• Avoid water, condensation, freezing, excessive vibration, impacts and drops
• After a long period of non-use, preheat the sensor for at least 24 hours
• Qualitative measurement only: do not use in systems involving personal safety
