Yosemitech Y515-A Online Chlorophyll Sensor adopts leading optical technology. According to the spectral absorption characteristics of chlorophyll a, the water body is illuminated by a high-energy LED light source to stimulate the chlorophyll a in the water to produce fluorescence of a specific wavelength, and the concentration of chlorophyll a in the water is measured. Chlorophyll-a is the primary photosynthetic pigment of algae and fluoresces when exposed to specific wavelength. Chlorophyll-a measurement can be used to assess living algae biomass of the bulk water. In numerous industrial and process related applications.
