Dissolved Oxygen Sensor – OPD790

Dissolved oxygen refers to molecular oxygen dissolved in water, usually recorded as DO, expressed in milligrams of oxygen per liter of water and saturation percentage. The saturated content of dissolved oxygen is closely related to the partial pressure of oxygen in the air, atmospheric pressure, water temperature and water quality. Dissolved oxygen plays a decisive role in actual sewage and wastewater treatment operations. The deterioration or excessive fluctuation of this indicator will often lead to large fluctuations in the stability of the activated sludge system, which will naturally have a very obvious impact on the treatment efficiency. The OPD790 Online Dissolved Oxygen Sensor developed and produced by Daruifuno adopts the principle of optical method, digital communication, internal storage of calibration data, and is plug-and-play. Paired with the DUC2-DO online Dissolved Oxygen Controller, it can realize continuous online monitoring of the dissolved oxygen value of sewage and wastewater, and control the dissolved oxygen content in the water. Dissolved oxygen in industrial wastewater is one of the important indicators to measure the quality of water bodies. High-quality water bodies are mainly because the water contains enough oxygen to maintain the oxygen demand in the ecological system. However, in the process of industrial production, industrial wastewater will bring a large number of chemical pollutants, which will consume oxygen in the water and reduce the dissolved oxygen content in the wastewater. Therefore, monitoring the dissolved oxygen content in industrial wastewater is of great significance for judging the quality of water and treating wastewater.
