Why Size Matters for Infra-red Gas Sensors? - Nenvitech

For some gases (such as refrigerants and sf 6) the only possible option is the larger sensor, since a 20 mm package would not a provide a large enough optical path to efficiently detect those gases. Hence, if you plan to measure carbon dioxide or especially flammable gases, and you have space available in your design, we would recommend choosing
