Abstract: The present invention relates to a gas measuring device (1) which is mobile, such as able to be sent into space, for performing a measurement relating to a concentration of a gas, such as nitrogen oxides, such as nitrogen dioxides, in a gas mixture such as air, comprising: - a reaction chamber (2) suitable for holding a reaction mixture for the purpose of bringing the gas into contact therein with the reaction mixture; - gas feed means (3), such as comprising a gas mixture feed tube, for feeding the gas mixture to the re¬ action chamber (2); - gas discharge means (4), such as comprising a gas mixture discharge tube, for discharging gas from the reaction chamber (2); - at least one photoelectric element (5), such as a photodiode, for converting photons, which are preferably released during a reaction between the gas and the reaction mixture, to electrical energy; - a processing circuit (31), such as an amplification circuit for a sampling circuit, for the purpose of providing a signal for sampling corresponding to a value of the released photons.
