Abstract
A gas sensor is provided that is delimited from the environment with a preferably replaceable cap () made of a porous, gas-permeable and water-impermeable material, especially sintered PTFE. The gas sensor is protected against environmental moisture and can be permanently provided with the cap () and with a special calibrating adapter () both during the gas measurement and during the necessary calibration. Due to the special design of the cap () and the calibrating adapter (), the gas sensor offers the possibility of remote calibration, which can be carried out with high accuracy and is independent from weather effects, especially wind.
