The working principle of this sensor is to use the characteristics of chlorophyll in the spectrum. By emitting light of a specific wavelength to iluminate the water body, chlorophyll will release fluorescence of another wavelength after absorbing the energy of the light. Then the intensity of this fluorescence is measured by using relevant detectiortechnology. The fluorescence intensity is proportional to the content of chlorophyl in the water body, so the concentration of chlorophyll can be indirectly determined. It has a self-cleaning function to remove attachments in water samples maintenance-free, no sample processing and extraction, non-destructive, reagent-free, pollution-free, accurate measurement, low detection limit, and good long-term stability, Long-life LED light source, built-in optical attenuation compensation, longer sensor life. Plug and play, no calibration required for first use.

Application fields: aquaculture, environmental monitoring, drinking water source monitoring, sewage treatment.
