Online Dissolved Oxygen Sensor Probe for Wastewater

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 a…
