>> Application
The online monitoring system can be real-time, continuous and accurately monitoring of the water, it can achieve a comprehensive understanding of the water quality for the management department, and prevent and timely find pollution accidents to provide auxiliary decision-making function. Also, this water quality monitoring system can reflect water environment to provide supporting for emergence dispatching. The main monitoring indexes of the system are pH, turbidity, conductivity, dissolved oxygen, temperature, Redox potential and other conventional parameters, but also can monitor COD, ammonia nitrogen, total phosphorus, total nitrogen and other pollutant parameters, at the same time, it also can expand chlorophyll, blue green algae, oil in water, nitrate and so on.
The system is especially suitable for on-line water quality monitoring of urban water environment control, urban ecological restoration and water source.
>> Characteristics
The system does not need to pump water, in situ measurement, so as to solve the problem of water quality change in the measurement process;
The system does not need much space, simple structure, easy installation, easy maintenance and management, simple operation;
Convenient layout, can be dragged to move;
The monitoring system equipment has reliable performance, low power consumption, and anti-humidity, lighting protection, anti-interference, etc. All acquisition can be unattended under the condition of long-term continuous normal work;
Modular design, string expansibility. The system can be expanded according to the use of meteorological, flow, liquid level and other monitoring and analysis instruments;
Solar power supply, free of wiring difficulties, can ensure long-term stable work.
