1. Micro water quality monitor product introduction:
Micro water quality monitor is a water quality monitoring device for rivers, canals, lakes, pools and other scenarios. It can monitor five parameters of conventional water quality.In response to the national strategic policy on strengthening environmental protection, maintaining the balance of natural ecology, and promoting the sustainable development of the national economy, and based on market needs, our company independently developed and produced the outdoor small automatic water quality monitoring station FT-WMSM, which combines the methods stipulated in the national standard with advanced Combining advanced computer technology, the measurement process is fully automated and can be widely used for surface water quality monitoring in rivers and lakes.
The factors causing eutrophication of surface water are mainly chemical factors such as N, P, organic matter, and HN4- in the water body.Therefore, monitoring chemical indicators such as total phosphorus, total nitrogen, ammonia nitrogen, chemical oxygen demand, and permanganate index of surface water has been It has become a necessary task to coordinate with the simultaneous monitoring of five conventional parameters (dissolved oxygen, turbidity, conductivity, temperature, pH) to comprehensively reflect water environment indicators.
2.Micro water quality monitor monitoring principle:
This outdoor water station adopts an integrated design principle and includes 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), and a quality control unit., auxiliary units (waste liquid collection, lightning protection, air conditioning, etc.).The core unit is the detection unit, total phosphorus, total nitrogen, chemical oxygen demand, permanganate index, ammonia nitrogen, chemical analysis methods that strictly follow the national standards.Conventional five parameter indicators (dissolved oxygen, conductivity, turbidity, temperature, pH) are measured using multi-electrode integration.
