Investigated of the physico-chemical properties of nickel hydroxide and tungsten trioxide films and their effect on gaschromic processes in the atmosphere of CO, chlorine and hydrogen; The factors influencing the selectivity and sensitivity of these films are determined. It has been established that for determination of CO, chlorine and hydrogen in their gas mixtures it is necessary to use Ni (OH) 2 films of different thicknesses using filter elements. On the basis of WO3 / Pd and NiOOH films, visual sensors and laboratory models of H2 and CO2 selective determination sensors were developed; The sensitivity of the sensors to these gases was ~ 1-2 vol.% (for visual sensors) and 0.01-1.1 vol.% (for laboratory models). Metrological support of the procedure for determination of CO, chlorine and hydrogen in gas mixtures and quality control of films for sensory elements have been developed.
