The digital chlorophyll sensor uses the characteristic that chlorophyll A has absorption peaks and emission peaks in the spectrum. It emits monochromatic light of a specific wavelength and irradiates water. The chlorophyll A in water absorbs the energy of the monochromatic light and releases a monochromatic light of another wavelength Color light, the intensity of light emitted by chlorophyll A is proportional to the content of chlorophyll A in water. Application: It's widely used for online monitoring of chlorophyll A in water plant imports, drinking water sources, aquaculture, etc ; online monitoring of chlorophyll A in different water bodies such as surface water, landscape water, and seawater.
