With the acceleration of industrial production and urbanization, the problem of water environment pollution is becoming more and more serious. As an efficient and accurate water quality monitoring equipment, dissolved oxygen monitor is gradually becoming an important tool in the field of environmental protection. This article will introduce you to the principle, characteristics and application of **dissolved oxygen monitor, to help you better understand this equipment and protect the health of the water environment.
1. The principle of dissolved oxygen monitor.
*A dissolved oxygen monitor is an instrument that measures the amount of dissolved oxygen in water in real time through an electrochemical sensor. It works by taking place an electrochemical reaction inside the electrode, and when dissolved oxygen in the water reacts with the metal film on the surface of the electrode, electrons and holes are generated. Electrons flow into the reference electrode in the inner shell, while holes flow to the indicator electrode in the outer shell. By measuring the current change between these two electrodes, the concentration of dissolved oxygen in the water can be calculated.
Second, the characteristics of the dissolved oxygen monitor.
1.Strong real-time: **Dissolved oxygen monitor can monitor the changes of dissolved oxygen in water in real time and continuously, effectively avoiding the measurement error caused by sampling time and transmission delay of traditional stations.
2.High accuracy: Due to the use of electrochemical sensors, the dissolved oxygen monitor has high measurement accuracy and stability, which can meet various water quality monitoring needs.
3.Strong anti-interference ability: **Dissolved oxygen monitor has good anti-electromagnetic interference ability, which can maintain stable measurement results in complex environments.
4.It can be widely used in various occasions: **Dissolved oxygen monitor is suitable for sewage treatment, water plant, ocean observation and other fields, providing strong support for environmental protection work.
3. Application of dissolved oxygen monitor.
1.Sewage treatment: **Dissolved oxygen monitor can monitor the water quality indicators in the sewage treatment process in real time to ensure that the sewage discharge meets the national standard.
2.Waterworks: By monitoring the dissolved oxygen concentration at the inlet and outlet, the water quality of the tap water can be safe.
3.Ocean observation: **Dissolved oxygen monitor can be used to monitor the marine ecological environment, understand the growth of marine organisms, and protect marine resources.
4.Industrial production: In some enterprises that produce organic wastewater, dissolved oxygen monitors can be used to monitor the dissolved oxygen content in wastewater in real time to ensure that the wastewater treatment effect meets the requirements.
