Online monitoring instrument for water quality: ensuring the safety of urban water supply quality and building a healthy defense line for residents' daily water use. [Model: TH-QSZ05, IoT integrated device, customized service supported by Yunjing Tianhe]As the lifeline of residents' lives, the water quality and safety of urban water supply systems are directly related to public health and social stability. However, sudden pollution in water sources, aging and corrosion of water supply pipelines, and improper management of secondary water supply facilities may all lead to deterioration of water quality and threaten the daily water safety of residents. Traditional manual testing, due to limited frequency and insufficient coverage, is difficult to detect abnormal fluctuations in water quality in a timely manner, which can easily lead to the accumulation of hidden dangers and risks. The deployment of online monitoring devices for water quality has built a real-time protective barrier for urban water supply safety. This device can continuously monitor core indicators such as residual chlorine, turbidity, pH value, and heavy metal content 24 hours a day by installing high-sensitivity sensors at key nodes such as water source intake, water treatment process, and pipe network ends. The data is uploaded to the management platform in real-time. Once the water quality parameters deviate from the safety threshold, the system immediately triggers the warning mechanism and synchronously pushes them to the water supply enterprise and regulatory department, providing scientific basis for quickly identifying pollution sources, adjusting treatment processes, and safeguarding the "last mile" of residents' water safety.
