PROBLEM TO BE SOLVED: To obtain a nitrogen monoxide oxidation converter that has a dehumidification function, has a relatively simple structure, can be miniaturized, and can be maintained easily and at the same time obtain an NOx measuring device for measuring a total NOx concentration using the nitrogen monoxide oxidation converter with the dehumidification function. SOLUTION: A nitrogen monoxide oxidation converter with a function for dehumidifying a supply gas and a function for oxidizing NO in a supply gas to NO2 is constituted. A proton conductor 10 is pinched by electrodes 11 and 12 and a voltage is applied to the electrodes by a power supply 13. A gas containing NO and NO2 is introduced into a reaction room 14 from a gas supply port 15, is brought into contact with the electrode 12, thus generating a reaction for exposing a dehumidification function and a reaction for exposing an oxidation function. Then, the NO is converted to NO2 and is led out of a gas exit 16. Also, a detector that responds to the NO2 of the led gas is provided, thus constituting an NOx measuring device. |
