Water Quality Online Monitoring System: Supports simultaneous monitoring of multiple parameters, with sampling intervals up to seconds, comprehensively reflecting the water quality status. [Model Recommendation: TH-QSZ06, IoT integrated device, customized service supported by Yunjing Tianhe] The water quality online monitoring system integrates high-precision sensors, high-speed data collection, and intelligent analysis technology to achieve real-time and accurate monitoring of water quality at key nodes such as water sources and water intakes. The system adopts modular design and supports dynamic parameter adjustment according to monitoring needs. The sampling interval of traditional monitoring system is usually minute or hour level, which is easy to miss short-term pollution events (such as non-point source pollution caused by chemical leakage and rainstorm scouring). Sensors based on principles such as photochemistry, electrochemistry, and spectroscopic analysis, with a response time of ≤ 1 second, supporting continuous and uninterrupted sampling; Deploy independent collection modules at critical nodes of water intake and pipelines to avoid data interruption caused by single point failures; In a sudden benzene leakage incident at a chemical plant, the system continuously monitored at a frequency of 1 second per occurrence and captured an abnormal surge in benzene concentration from 0mg/L to 5mg/L at the water intake within 30 seconds, in order to fight for critical time for the emergency shutdown of downstream water plants.
