Dissolved oxygen meter is an instrument used to measure the dissolved oxygen content in liquids. It typically uses electrochemical or optical sensors to detect dissolved oxygen levels in liquids. Electrochemical sensors measure the reduction or oxidation reaction of oxygen by immersing it in a liquid and applying an electric current to determine the concentration of dissolved oxygen. Optical sensors use the absorption and scattering characteristics of light to measure the concentration of dissolved oxygen.

Dissolved oxygen meters are widely used in fields such as water quality monitoring, environmental science, aquaculture, and life sciences. In water quality monitoring, dissolved oxygen meters can be used to evaluate the redox conditions of water bodies and the health status of ecosystems. In aquaculture, dissolved oxygen meters help control the oxygen supply in the water, ensuring the living environment of fish or other aquatic organisms. In addition, dissolved oxygen meters are also used in laboratory research and industrial process control.
