In a device for measuring the concentration of a reagent from the group of the gases reacting acidically or basically in an aqueous environment, and also volatile acids and bases in a liquid or gaseous sample, with a sample space arranged in a housing, and a device for determination of the pH value with a reaction space which is separated from the sample space by an ion-impermeable, gas-permeable membrane, filling of the reaction space with buffer solution is facilitated in that the reaction space (8) is connected by an ion-permeable channel (7) with a reservoir (11), which can be filled with buffer solution, outside the device (4) for the determination of the pH value. <IMAGE> |
