Fluorescence dissolved oxygen apparatus
9600 series industrial on-line dissolved oxygen apparatus is a water quality on-line monitoring and control instrument with microprocessor.
The instrument is equipped with different types of dissolved oxygen electrode widely used in power plants, petrochemical, metallurgical electronics, mining, paper industry, food and beverage, environmental protection water treatment, aquaculture and other industries;
The dissolved oxygen value and temperature value of aqueous solution are continuously monitored and controlled.
