MEJ-DO7017 optical dissolved oxygen sensor is a new type of water quality monitoring equipment. It is based on the principle of fluorescence quenching, and accurately measures the dissolved oxygen content in water by detecting the change in fluorescence intensity of fluorescent substances after contact with oxygen.
The sensor has a wide measurement range and a resolution of up to 0.01mg/L, which can meet the high-precision measurement requirements in various environments.
Characteristics:
Range: 0.00 to 20.00 mg/L
Accuracy:3%
Resolution: 0.01
Signal interface: Modbus RS-485
Intro to MEJ-DO7017 Optical dissolved oxygen sensor
It has the advantages of fast response speed and no need for frequent calibration, reducing maintenance workload compared to traditional electrochemical sensors.
Meanwhile, DO7017 is equipped with RS485 digital interface and supports Modbus RTU protocol, which facilitates remote communication and data transmission with various data acquisition systems.
In practical applications, whether it is the real-time monitoring of dissolved oxygen in water bodies in aquaculture, the precise control of process links in sewage treatment plants, or the long-term monitoring of environmental water bodies such as Rivers and Lakes.
DO7017 can provide users with accurate dissolved oxygen data by virtue of its stable and reliable performance, helping production management and ecological environment research.
