Online Dissolved Oxygen Analyzer | Meter

Online dissolved oxygen analyzer is a Water Quality Monitor that accurately measures and controls the dissolved oxygen level in water online. It is also commonly called a dissolved oxygen meter. It consists of a controller connected to a sensor to achieve continuous real-time monitoring of the dissolved oxygen value of water quality. The controller display of our DUC2-DO online dissolved oxygen analyzer is 3.2 inches, which can display a lot of information. It has two relays and two 4-20mA current outputs. It also has an RS485 interface and supports Modbus protocol digital transmission. The DO Sensor uses fluorescence to measure the dissolved oxygen content. Its advantages are that it does not require reagents, does not consume oxygen, and can be measured in real time.

Dissolved oxygen (DO), as an indispensable key element of life activities in water bodies, refers to oxygen molecules dissolved in water. It is the main source of respiration for aquatic organisms and is directly related to the health and stability of aquatic ecosystems. High dissolved oxygen levels can support the survival of more types of aquatic organisms and promote biodiversity. It also helps the natural degradation process of organic matter in water bodies and reduces the accumulation of pollutants.

The importance of monitoring dissolved oxygen lies in that it is not only one of the key indicators for evaluating water quality conditions, but also an important basis for judging the self-purification capacity of water bodies and the health of ecosystems. Low dissolved oxygen levels may cause aquatic organisms to suffocate and die, destroy the ecological balance, and even cause environmental problems such as eutrophication and black and smelly water. Therefore, timely and accurate monitoring of dissolved oxygen content is of great significance for preventing water quality deterioration, protecting water resources, and maintaining ecological balance.

Online digital dissolved oxygen analyzer plays an indispensable role in water quality monitoring in many industries due to its high precision and real-time continuous monitoring characteristics:

Environmental protection: Installing online dissolved oxygen analyzers in natural water bodies such as rivers, lakes, reservoirs, and sewage treatment plant outlets can monitor water quality changes in real time, detect and warn water pollution incidents in a timely manner, provide scientific basis for environmental protection departments, and effectively protect the water environment.

Aquaculture: Dissolved oxygen is a key factor affecting the growth and health of aquatic animals. Installing analyzers in aquaculture ponds can accurately control dissolved oxygen concentrations, optimize the breeding environment, improve breeding efficiency and product quality, and reduce economic losses caused by hypoxia.

Drinking water treatment: Ensuring drinking water safety is the basis of public health. Online monitoring of dissolved oxygen helps evaluate the effectiveness of water treatment processes, such as ozone disinfection and biofilters, to ensure that water quality meets standards and that residents’ drinking water is safe.

Industrial cooling water management: In the industrial field, especially in the power and chemical industries, the dissolved oxygen content of the cooling water system directly affects the corrosion rate of equipment and the cost of water treatment. Through online monitoring, the cooling water treatment plan can be adjusted in time to extend the life of the equipment and reduce operating costs.

Hot spring and swimming pool management: For recreational water bodies such as hot springs and swimming pools, the monitoring of dissolved oxygen helps maintain the cleanliness of the water, prevent the spread of diseases, and improve user experience.
