Dissolved Oxygen measurement can be applied in avariety of industries and applications where accurate measurement and control is required to improve and optimize processes. Dissolved Oxygen is a term used for the measurement of the amount of oxygen dissolved in a unit volume of water. In fish farming the level of Dissolved Oxygen must be kept at a sufficient level or the fish will suffocate. Dissolved Oxygen measurement can indicate the condition of a river or reservoir and to control aeration equipment in a sewage works or wastewater treatment plant. In sewage treatment, where bacteria is used to decompose the solids, it is important to accurately control the Dissolved Oxygen level as when the level is too low, the bacteria die and decomposition stops. However in both of the above mentioned applications, when the Dissolved Oxygen level is too high, energy is wasted due to unnecessary aeration of the water but good accurate control of the aeration process can reduce running costs. Other applications include cell culture in biotechnology where the precise accurate measurement of Dissolved Oxygen and pH measurement is important in costly research and production applications.
