Product Introduction:

The outdoor small-scale water quality automatic monitoring system is a new type of online water quality monitoring product that has emerged to meet the requirements of high density, low cost, and high frequency in current environmental protection, water conservancy, or water management applications. It has the advantages of small installation volume, no need for land acquisition, complete quality control functions, and reliable operation, and can achieve functions such as river chief assessment, pollution tracing, water quality evaluation, and water quality warning. The outdoor small-scale water quality automatic monitoring system consists of a water collection unit, a pre-treatment and distribution unit, an analysis unit, a data acquisition and transmission unit, a control unit, an auxiliary unit, etc. It can also be equipped with a quality control unit and a remote monitoring platform.

Product Principle:

In the presence of potassium persulfate, nitrogen-containing compounds in the water sample undergo high digestion and are completely converted into nitrate nitrogen. After cooling to room temperature, they react with the indicator to form a colored complex. The monitor detects this color change and converts it into the total nitrogen value output.
