Measure the Concentration of Oxygen Dissolved in Liquids, Particularly Water.
DO 4300 is a Dissolved Oxygen (DO) Analyser which is an analytical instrument used to measure the concentration of oxygen dissolved in liquids, particularly water. Dissolved oxygen is one of the most important parameters for assessing water quality because it directly affects aquatic life, biological treatment processes, and industrial water systems.
DO analysers are widely used in water treatment plants, wastewater treatment facilities, aquaculture, environmental monitoring, power plants, and process industries.
