Yaxin-1168 Algae Fluorescence Dynamics Measurement System

Yaxin-1168The Algae Fluorescence Dynamics Measurement System is a professional scientific research grade chlorophyll fluorescence probe tool for aquatic plankton independently developed and produced by Beijing Yaxin Liyi Technology Co., Ltd.

In terms of appearance, it adopts professional industrial design concepts, with flowing color decorative lines and a large touch color screen,ABSEco-friendly material In terms of intrinsic quality, its chip computing power, storage capacity, strict selection of optical components, and compact structure endow the entire machine with excellent performance.

This instrument has a wide detection limit and can meet the detection needs of both natural water bodies and laboratory cultivated algae. It can be widely applied to the sampling and investigation of natural water bodies, such as ponds, lakes, swamps, rivers, and nearshore water environments. The research field includes but is not limited to algae (blue-green algae, green algae, red algae, brown algae, etc.) that contain chlorophyllaTeaching and research work on the photosynthesis mechanism of algae, algae stress physiology, breeding and screening of clean energy organisms, water bioremediation, lake and sea carbon sink systems, and biological tolerance.
