1.Micro water quality monitor product introduction:
In response to the country's strategic policies on strengthening environmental protection, maintaining natural ecological balance, and promoting sustainable development of the national economy, and based on market needs, our company independently developed and produced the outdoor small-scale automatic water quality monitoring station FT-WMSM, which combines the methods specified in the national standard with advanced computer technology to achieve full automation of the measurement process. It can be widely used in surface water quality monitoring of rivers, lakes, etc.
The factors that cause eutrophication of surface water are mainly chemical factors such as N, P, organic matter, HN4- and other chemical factors in the water body. Therefore, monitoring chemical indicators such as total phosphorus, total nitrogen, ammonia nitrogen, chemical oxygen demand, and permanganate index in surface water has become a necessary task. It is necessary to monitor the five conventional parameters (dissolved oxygen, turbidity, conductivity, temperature, and pH) simultaneously to comprehensively reflect the water environment indicators.
2. Micro water quality monitor monitoring principle:
This outdoor water station adopts an integrated design principle, including a water collection and distribution system, a detection unit (five measurement modules for total phosphorus, total nitrogen, chemical oxygen demand, permanganate index, ammonia nitrogen, and five conventional parameters), a quality control unit, and an auxiliary unit (waste liquid collection, lightning protection, air conditioning, etc.). The core unit is the detection unit, and the total phosphorus, total nitrogen, chemical oxygen demand, permanganate index, and ammonia nitrogen strictly follow the chemical analysis methods specified in the national standard. The conventional five-parameter indicators (dissolved oxygen, conductivity, turbidity, temperature, and pH) are measured using a multi-electrode integrated method.
