Ecological Systems and Devices Annotation << Back Sensor to control micro concentration of hydrogen sulfide Abdurakhmanov E., Abdurakhmanov B.M., Normuradov Z.N., Gevorgyan A.M. In the course of the experiment optimal values of the consuming sensor voltage (TKS-N2S-3м) have been selected, dynamic, gradual characteristics and selectivity of the work studied. The sensor providing determination selectivity of hydrogen sulfide in multicomponent gas-air mixtures, where hydrogen, carbon oxide and methane (natural methane gas) are simultaneously contained with hydrogen sulfide has been developed. Key words: thermocatalytical method; sensor; hydrogen sulfide; selective catalyst. E-mail: ergach50@yandex.ru
