FIELD: measuring methods.
SUBSTANCE: device, designs of the gas composition sensor, ammonia concentration sensors. The ammonia vapor concentration sensor in the air is made on a dielectric substrate with current interpenetrating contacts of a comb type made of aluminum deposited on it and on which a conductive polymer film is deposited. The film is made on the basis of a derivative of polyaniline poly-2-(cyclohex-2-en-1-yl)aniline in the area of the gap between the contacts.
EFFECT: increasing the accuracy of determining the presence and concentration of ammonia vapor.
