Device in which the component to be detected is absorbed in a reactive solution and in which, on the basis of a reaction between the component and the reactive solution using electrodes in the reactive solution, a change in resistance of the reactive solution is determined as the measurement magnitude by means of a resistance measurement device, the measurement gas entering a test container by passing through a sealing element which allows the fluid to be detected to pass but is hermetically sealed against the reactive solution. According to the invention, the reactive solution 2 contains a strongly dissociated solution which makes a weakly dissociated combination with the component to be detected. Application to measuring the alcohol content in human breath. <IMAGE>
