Online Chlorophyll Analyzer utilizes a fluorescence-based method for the stable acquisition of water quality monitoring data

Online Chlorophyll Analyzer employs a fluorescence-based detection technique with a measurement range of 0 to 400 µg/L, while simultaneously recording water temperature. It achieves a correlation coefficient greater than 0.999 and a resolution of 0.01 µg/L. The device supports the integration of various multi-parameter sensors to suit diverse monitoring environments. It automatically stores monitoring data and alarm records, allows for local data export, and is equipped with an RS485 interface. By adhering to the MODBUS-RTU communication protocol, it can seamlessly connect to standard automation and transmission equipment—such as PLCs, DCS, SCADA/configuration software, and DTUs—ensuring stable data transmission.

Online Chlorophyll Analyzer is an online monitoring instrument designed for the detection of water eutrophication. It continuously measures chlorophyll concentration using the principle of fluorescence detection. The process requires no complex sample pre-treatment, offers rapid response times, and delivers stable results, making it ideal for long-term, continuous field monitoring. In addition to its core chlorophyll and water temperature monitoring capabilities, the instrument features expansion channels. Users can integrate supplementary water quality sensors—tailored to specific requirements for rivers, reservoirs, water sources, or aquaculture—to build a multi-parameter monitoring system, thereby reducing the overall deployment costs.

Online Chlorophyll Analyzer includes comprehensive data storage functionality, continuously recording real-time values during operation and automatically saving alarm details whenever thresholds are exceeded. Users can export historical records as needed for trend analysis, record-keeping, and traceability verification. Utilizing an industry-standard RS485 interface and the MODBUS-RTU protocol, the device is compatible with most industrial automation equipment. Once connected to a configuration platform or remote transmission terminal, monitoring data can be uploaded in real-time to a central control system, enabling remote viewing and centralized management, which reduces the need for frequent manual on-site inspections. The Online Chlorophyll Analyzer is designed for outdoor, submerged installation and features robust anti-interference capabilities, making it well-suited for the dynamic conditions of natural water bodies. It is deployed in applications such as surface water monitoring, water source early warning, and aquaculture management, providing continuous, reliable data for monitoring algae and assessing the risk of eutrophication. Its standardized communication design allows for seamless integration into existing online monitoring stations; this facilitates system upgrades without requiring major modifications to the original automation architecture, thereby simplifying project implementation and ongoing maintenance.
