Dissolved Oxygen Sensor With RS485 For Industrial Process Sewage
OPD701 dissolved oxygen sensor adopts the measurement principle of fluorescence method, which has the advantages of high sensitivity, wide measurement range, real-time monitoring and remote monitoring. These characteristics enable the fluorescence sensor to provide accurate and reliable monitoring of dissolved oxygen concentration in the process of industrial sewage treatment, helping to optimize process control and improve treatment effect.
Industrial sewage dissolved oxygen sensor is a sensor used to monitor the concentration of dissolved oxygen in industrial sewage. Industrial effluents often contain a variety of organic and inorganic substances, as well as pollutants that can lead to lower dissolved oxygen concentrations.
Therefore, industrial sewage dissolved oxygen sensors need to have anti-pollution performance, fast response and high precision, corrosion resistance, real-time monitoring and remote communication functions, as well as sustainable operation and easy maintenance to meet the requirements of industrial sewage treatment. Specific industrial wastewater characteristics and treatment needs are selected.
