Automatic surface water quality monitoring stations serve as core infrastructure for watershed environmental management, cross-section assessment, pollution tracing and early warning. They are widely deployed in rivers, lakes, reservoirs, drinking water sources and transboundary monitoring sections. Shandong Dongrun Instrument delivers a full-process integrated turnkey construction solution.
Complying strictly with surface water monitoring standards, our solution adopts multiple station types according to on-site hydrological conditions and land availability, including container-style station houses, shore-mounted integrated cabinets and miniature monitoring stations.
The system integrates water sampling unit, water sample pretreatment, online analyzers, automatic quality control, sample retention and data acquisition & transmission modules. It conducts real-time monitoring of pH, dissolved oxygen, ammonia nitrogen, total phosphorus, total nitrogen, permanganate index, turbidity, water temperature and other parameters.
Equipped with automatic cleaning, auto-calibration and over-limit sample retention functions, the system filters sediment and impurities through the pretreatment unit to ensure stable and reliable long-term monitoring data in field environments.
Supporting the HJ212 protocol, the system enables direct data upload to environmental supervision platforms. Functions including remote viewing, historical trend analysis and multi-level over-limit alarms are available. Water samples will be automatically stored once water quality anomalies occur, providing evidence for pollution source tracing.
The station is equipped with constant temperature control, lightning protection, UPS uninterruptible power supply and anti-theft monitoring systems, adapting to harsh field conditions such as high humidity and large temperature fluctuations.
With extensive experience in watershed monitoring station projects, Shandong Dongrun Instrument provides one-stop services: site survey, solution design, equipment supply, installation & commissioning, comparative acceptance and after-sales maintenance. We help build an all-weather automated watershed water quality monitoring network to support refined water environment governance.
