DUC2-DO Dissolved Oxygen Controller for Water Treatment

Dissolved oxygen refers to oxygen molecules dissolved in water. Dissolved oxygen in water is very important for maintaining the survival and growth of aquatic organisms. Several common principles for monitoring dissolved oxygen are: electrode method, reagent method, spectroscopic method, optical method, etc. Daruifuno's online Dissolved Oxygen Controller is a digital instrument. It can be connected with a digital fluorescent Dissolved Oxygen Sensor to realize continuous real-time monitoring of the dissolved oxygen value of water quality. The advantage of measuring dissolved oxygen content by fluorescence method is real-time measurement without reagents and oxygen consumption. The display screen of the controller is 3.2inch, it can display much information. As a controller, this dissolved oxygen analyzer has two relays and two 4-20mA current outputs, it also has RS485 interface and support Modbus protocol.

In some specific water treatment processes, such as sewage treatment and drinking water treatment, the monitoring of dissolved oxygen content can help evaluate the treatment effect. For example, in sewage treatment, changes in dissolved oxygen content can reflect the degradation of organic matter in wastewater. By monitoring the dissolved oxygen content by the dissolved oxygen analyzer, it is possible to determine whether the treatment process is effective and to adjust the treatment plan in time.
