Utilizing fluorescence detection and digital intelligent design, this sensor features built-in temperature compensation, and supports calibration, data logging, analysis, and diagnostics. It uses an RS485 interface and standard Modbus protocol for real-time online monitoring of cyanobacteria.
When exposed to excitation light of a specific wavelength, cyanobacteria are stimulated to a higher energy state. As they return to their ground state, they emit fluorescence with a longer wavelength than the excitation light. The intensity of the emitted fluorescence is directly proportional to the concentration of cyanobacteria in the water.
