SEM9850-YLChlorophyll online analyzer
Chlorophyll online analyzerMeasurement principle:
The chlorophyll sensor utilizes the characteristic of chlorophyll A having absorption and emission peaks in the spectrum, emitting monochromatic light of a specific wavelength into water. Chlorophyll A in the water absorbs the energy of this monochromatic light and releases monochromatic light of another wavelength. The intensity of chlorophyll A emitted is proportional to the content of chlorophyll A in the water.
Functional features:
ØIt is a fluorescence measurement target parameter based on pigmentsCan be identified before potential algal blooms have an impact;
ØNo need for extraction or other processing, rapid detection,Avoid the impact caused by shelving water samples;
ØDigital sensors with strong anti-interference ability and long transmission distance;
ØStandard digital signal output, which can be integrated and networked with other devices without a controller;
ØThe on-site installation of sensors is convenient and fast, achieving plug and play functionality.
Typical applications:
ØOnline monitoring of chlorophyll in water plant imports, drinking water sources, aquaculture, etc;
ØOnline monitoring of chlorophyll in different water bodies such as surface water, landscape water, and seawater.
