Yaxin-1168 Aquatic Chl-Fluo kinetic measurement system can be widely used in sampling and studying natural water bodies such as ponds, lakes, marshes, rivers, offshore and other water environments. The research fields include, but are not limited to, teaching and research work on photosynthesis mechanism of algae (cyanobacteria, green algae, red algae, brown algae and other chlorophyll a-containing algae), algae stress physiology, clean energy biological breeding and screening, water bioremediation, lake and sea carbon sink system, biological tolerance and so on.
