The LGS-02 Surface Water Quality Online Automatic Monitoring System developed by Landun Photoelectron is a robust, advanced, intelligent and fully integrated online monitoring platform centered on an online water quality analyzer. Adopting modern sensor, automatic measurement, automatic control, computer and communication technologies, the system delivers real-time, continuous automatic water quality monitoring and remote management. It provides timely status feedback and early warning for surface water pollution incidents, offering real-time, precise and comprehensive data support for environmental supervision and decision-making authorities.

System Components

This automatic surface water quality monitoring system comprises water sampling unit, water distribution & pretreatment unit, analysis unit, control unit, data acquisition & transmission unit and auxiliary modules. It automates the full workflow including water intake, distribution, pretreatment, analysis and data transmission, and is equipped with complete quality control functions: automatic calibration verification, automatic duplicate sample testing and automatic spike recovery testing.

Monitoring Indicators

Measuring items can be flexibly configured based on site water conditions, covering standard five fundamental parameters (water temperature, pH, conductivity, dissolved oxygen, turbidity), plus chemical oxygen demand, permanganate index, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, total nitrogen, total phosphorus, TOC, chlorophyll a, algal density, cyanide, fluoride, petroleum oil, hexavalent chromium, volatile phenols, heavy metals, total arsenic and flow rate.
