The B800 series online optical digital blue-green algae sensor’s principle uses the characteristics of cyanobacteria who has absorption peaks and emission peaks in the spectrum. The absorption peaks emit monochromatic light into the water, cyanobacteria in the water absorbs the energy of monochromatic light, releasing monochromatic light of emission peak of another wavelength. The light intensity emitted by cyanobacteria is proportional to the content of cyanobacteria in water.
The IUNI-21 dual channel analyzer is an effective option that can connect two digital blue-green algae sensors at the same time to reduce the cost of transmitter and installation space.
