product description
The CHL-2000 fluorescence method online chlorophyll analyzer uses an immersion sensor to measure the concentration of chlorophyll based on fluorescence method. This instrument is widely used in surface water monitoring, biological/environmental ecology research, seawater monitoring, water profile/navigation research and other fields.
Product principle
Under the excitation of an external 470nm light source, chlorophyll absorbs light in a certain visible spectral region (mainly in the red and blue light regions) and releases a small amount of absorbed energy in a fluorescent manner near a longer wavelength of 680nm. By analyzing its absorption characteristicscountCalculate the concentration of chlorophyll in water.
