Abstract
The method operates on a flow of gas through two adjacent pipes, one (3) of which has a desiccator (2) ahead of its gas sensor (1). The second pipe (4) contains one or more sensors (5) preferably for at least one other component of the gas. The desiccator reduces the moisture content of the gas to less than 5% and is followed by a temperature sensor (6) and a humidity-measuring device (7) for compensation purposes. The flow through the first pipe is analysed by at least one sensor operating on a different principle and reducing the cross-sensitivities. USE - For atmospheric monitoring in workplace, dwellings and environment. CO2 content can be measured with sufficient precision and sensitivity.
