Chlorophyll Controller

The function of the water quality chlorophyll controller is to monitor and control the concentration of chlorophyll in the water body to maintain the stability and safety of the water quality. It can be connected with a digital Chlorophyll Sensor to continuously monitor the chlorophyll value of water quality. By monitoring the concentration of chlorophyll in the water, the degree of eutrophication of the water body can be assessed, and algae outbreaks in the water body can be detected and warned in time, as well as other pollution sources that may cause eutrophication of the water body. According to the concentration change of chlorophyll, the two relays or 4-20mA current output of the water quality chlorophyll controller can automatically adjust the operating parameters of the water treatment system, such as adjusting the aeration amount, adding chemicals, etc., to maintain the stability and safety of water quality . The water quality Chlorophyll Analyzer can monitor the chlorophyll concentration in the water body, help the farmers to grasp the water quality, take timely measures to adjust the breeding environment, and prevent the deterioration of the water quality from causing harm to the breeding organisms. It can also be used for the management of lakes, rivers and other waters, to monitor the concentration of chlorophyll in the water, to detect and warn of eutrophication in time, so that corresponding management measures can be taken to protect the health of the water ecosystem.
