Ecological Systems and Devices Annotation << Back Research of channel of express measurement of dissolved oxygen concentration in water with electrochemical element D.L. Gouralnik, K.E. Kassatsier, U.F. Fedorenko The dependence of sensibility and time constant of the water-dissolved oxygen concentration sensor, based on Clark cell, from cell construction parameters and temperature was theoretically and experimentally researched. Recommendations for measurement errors reduction are given. Key words: dissolved oxygen concentration sensor; express measurement; water area ecological control. E-mail: guralnikdl@mail.ru Pp:13-19
