IP66 RS485 Interface Chlorophyll Meter For Surface Water Monitoring
The importance of chlorophyll A:
Chlorophyll A is one of the important components of algae cells,
all algae contain chlorophyll A;
The content of chlorophyll A is closely related to the type and
quantity of algae in the water body;
The light energy absorbed by chlorophyll B, C, D 3 types of
photosynthesis will eventually be transmitted to chlorophyll A,
which is transmitted to the chemical reaction system;
Determination of the common content of chlorophyll A can reflect
the amount of algae in the water and the water quality to a certain
extent.
