FIELD: analytical instrumentation engineering. SUBSTANCE: sensor of vapors of asymmetrical dimethylhydrazinal has nonconductive base on which electrodes and sorbing sensitive coat is deposited. Base and electrode form quartz resonator. Polymer carbonic acid of series of weak polymer carbonic acids or copolymer of styrene with weak carbonic acid is used in the capacity of sorbing coat deposited on electrodes. Polymaleic, polyacrylic or polymetacrylic acid or copolymer of styrene with maleic acid is used as coat. EFFECT: simplified manufacturing process. 4 cl, 1 dwg , 1 tbl
