The MG3200 Fluorescence Dissolved Oxygen Analyzer is a high-performance online water quality monitoring instrument equipped with a microprocessor. It is designed for continuous monitoring and control of oxygen content in aqueous solutions, relying on the fluorescence quenching effect and advanced phase method technology. This instrument features an LCD screen and intelligent Chinese menu operation, making it user-friendly for operators in various industries. With multiple output options and automatic calibration functions, it stands out as a reliable solution for real-time dissolved oxygen detection in industrial water, domestic water, sewage treatment, and animal husbandry scenarios.
Adopting the most advanced phase method technology and Mega-tek imported process, the analyzer ensures high stability with weekly drift < 2% FS under normal pressure and constant temperature conditions. It eliminates the need for electrolyte membrane head replacement, and the fluorescence cap has a long service life of more than two years, greatly reducing maintenance costs.
The instrument does not consume oxygen during measurement and has no flow rate or agitation requirements, allowing flexible deployment in static or dynamic water bodies. It is not interfered by H₂S, pH, CO₂, NH₄⁺, Cl⁻, Cl₂ and other substances, ensuring accurate data even in complex water environments.
Equipped with a digital signal sensor, it has strong anti-interference ability and long transmission distance. Supporting RS485 signal output and standard Modbus communication protocol, it can be seamlessly integrated and networked with various terminal devices, realizing centralized data management.

In municipal sewage treatment plants, the MG3200 Fluorescence Dissolved Oxygen Analyzer monitors dissolved oxygen levels in real time to optimize the aeration process. Maintaining appropriate oxygen content can improve the activity of aerobic microorganisms, enhance the decomposition efficiency of organic pollutants, and ensure the effluent quality meets the discharge standards.
For industrial wastewater treatment systems, especially in sectors such as chemical and printing and dyeing, the analyzer provides stable dissolved oxygen data. It helps adjust the operation parameters of treatment equipment in a timely manner, avoiding excessive energy consumption caused by insufficient or excessive aeration.
In aquaculture water bodies, dissolved oxygen is a key factor affecting the survival and growth of aquatic organisms. The instrument realizes continuous online monitoring of fish ponds and shrimp ponds, enabling farmers to take oxygenation measures in advance when the oxygen content is low, thus reducing the risk of aquatic product death and improving breeding efficiency.
In aeration tanks and aerobic/anaerobic digestion tanks, the analyzer can accurately reflect the oxygen status in the tanks. It provides a data basis for the operation control of the tanks, ensuring the stable progress of the biochemical reaction and improving the treatment effect of sludge and organic matter.
The electrode supports automatic calibration. Under normal use conditions, it is recommended to perform manual calibration once every 3 months to ensure measurement accuracy.
The standard process temperature range is 0～45℃ and 0～100℃. For higher temperature requirements, you can consult our sales staff for customized high-temperature models.
No. It supports multiple installation methods including immersion type, flow cell and flange. The installation steps are simple, and the user can complete the installation according to the operation manual.
