These stations are equipped with multiple high-precision water quality sensors that automatically collect various water quality indicators, remotely transmit monitoring data, and provide over-limit alarm functions. They are suitable for water quality management in rivers, aquaculture, and wastewater treatment plants.
Using various types of water quality sensors as their core hardware, pole-mounted water quality monitoring stations can routinely monitor six water indicators: water temperature, conductivity, pH, dissolved oxygen, ammonia nitrogen, and turbidity. Different sensors employ specific detection principles to ensure accurate and reliable monitoring results. The ammonia nitrogen sensor uses the ion-selective electrode method, covering a measurement range of 0-1000 mg/L; the pH sensor uses the electrochemical salt bridge principle, with a measurement range of 0-14; conductivity uses the contact electrode method; dissolved oxygen is measured using the fluorescence lifetime method; and turbidity is measured using the scattered light method. All sensors have fixed measurement accuracy and numerical resolution, providing stable and standardized monitoring values.
The pole-mounted water quality monitoring station integrates sensors, signal acquisition components, power supply hardware, and a wireless transmission module. The equipment uses a pole-mounted installation method, simplifying the deployment process. Solar power enables long-term unattended outdoor operation. After continuously collecting water parameters, the equipment uploads all monitoring data to an online management platform. Staff can remotely view real-time water quality data and monitor the station's operational status, eliminating the need for frequent manual on-site inspections.
The platform can store historical monitoring data long-term, automatically analyzing water quality trends. When any monitoring parameter exceeds preset thresholds, the system triggers an over-limit alarm, providing immediate alerts to staff. The system can also combine multiple water quality parameters to calculate a comprehensive water quality index, objectively and completely preserving water quality data. Currently, this monitoring equipment can be deployed in reservoirs, rivers, lakes, aquaculture ponds, and sewage treatment plants, providing 24/7 uninterrupted monitoring of water dynamics and outputting detailed and objective monitoring data. This provides reliable data support for water environment investigation and water pollution control, promoting the intelligentization of water environment management.
