Chapter 2 Product Overview

2.1 Product Information

chlorophyllSensors utilize the characteristic of chlorophyll having absorption and emission peaks in the spectrum. At the absorption peak of chlorophyll, monochromatic light is emitted and irradiated into water. Chlorophyll in water absorbs the energy of monochromatic light and releases monochromatic light with another wavelength emission peak. The intensity of chlorophyll emission is proportional to the content of chlorophyll in water. This sensor is easy to install and use. Widely used for water quality monitoring in sewage treatment plants, waterworks, water stations, surface water, industrial and other fields. configurationCHCThe controller can anthropomorphize the data measured by the sensor. Users can also achieve 4-20mA analog output through the interface configuration and calibration of the controller. Implement relay control and digital communication functions.
