Dissolved Oxygen Sensor

Dissolved oxygen sensors detect the concentration of dissolved oxygen in water through electrochemical or optical methods. Electrochemical types utilize electrodes to generate a current proportional to the oxygen concentration, while optical types operate based on the principle of fluorescence quenching. They are used in water quality monitoring, wastewater treatment, and aquaculture.
Selection
Select electrochemical or optical types based on the measurement environment. Electrochemical is suitable for routine monitoring, while optical offers strong anti-interference capabilities. Consider the measurement range to cover actual needs and ensure accuracy matches application standards. Check the corrosion resistance of the electrode material and the replacement cycle of the membrane. Confirm compatibility of the output signal with the equipment and evaluate maintenance costs.
