Water quality monitoring environment
Water quality environmental monitoring is the basis for rational use of water resources and protection of water resources. It is a strategic element directly related to people’s health. It is an important measure to implement sustainable development. Global water pollution is getting worse. Environmental monitoring of water quality is also receiving more and more attention. However, due to changes in the environment, climate, and water quality. Especially the online monitoring of rivers and lakes has become more difficult. The chlorophyll sensor that can be cleaned automatically by the river monitoring system makes the water quality monitoring more accurate.
Chlorophyll sensor features
The water chlorophyll meter has high-efficiency power management, sturdy structure, and stable sensor performance. Free of maintenance and frequent calibration. Can be used online for a long time. It can be used in rivers, lakes, ponds, marine surveys, and aquaculture. Research, investigation and monitoring of drinking water sources, algae and phytoplankton conditions. The water body chlorophyll measuring instrument has stable output signal and high precision. It has a wide measuring range, high stability and easy to use. Features such as easy installation and long transmission distance.
Selection of probes in sewage conductivity measurement
In the sewage test. The selection of a suitable industrial conductivity meter becomes the basis for monitoring. K is the conductivity probe coefficient. The lower the coefficient. The lower the range of conductivity. But the higher the unit precision. The higher the coefficient. The range of conductivity is very large. But the unit accuracy is low. Under normal circumstances. The conductivity of pure water is generally within 20us/cm. Therefore, the probe with K=0.01 can be selected. The conductivity of normal tap water or industrial water is within 200us/cm. So choose the probe with K=0.1. Sewage contains more ions. Therefore, the conductivity is relatively large, generally greater than 1000us/cm. Generally choose to use the probe with K=1. If there are some concentrated solutions, nutrient solutions, and salt solutions. Generally, the conductivity is greater than 10000us/cm. Need to choose K=10 probe.
