Measurements of Dissolved Oxygen Concentration in Stationary Water

The paper justifies the need for measuring the concentration of oxygen dissolved in stationary waters; in order to perform accurate measurements, the oxygen probe must be displaced inside water with a speed greater than 0,3 m/s. The performed experimental researches proved the accuracy of probe displacement and the reliability of the driving mechanism. The constructive solution of the driving mechanism, its functioning and the results of the performed measurements are exposed.
