Yaxin-1165Plant Fluorescence Dynamics Measurement System

Yaxin-1165Plant Fluorescence Dynamics Measurement System It is the third-generation chlorophyll fluorescence analyzer independently developed and produced by Beijing Yaxin Liyi Technology Co., Ltd. (hereinafter referred to as our company).

In terms of appearance, it achieves color touchscreen display and adopts humanized industrial design,ABSEco-friendly material In terms of intrinsic quality, there have been significant improvements in chip computing power, storage capacity, and optical path structure. The basic functions includeOJIPTheKautskyAnalysis, etc; Advanced features include dark delay, fast light curve, pulse transient fluorescence dynamics curve, etc; Innovative functions can be measured as follows:QA–Redox kineticsSMeasurement modes such as state transition dynamics. Truly achieved“as one pleases'Study on Chlorophyll Fluorescence Dynamics.

The instrument can be used for theoretical research on photosynthesis, study of electron transfer chains under environmental light fluctuations,“afternoon nap'Research on the mechanism of phenomena and the study of cyclic electronic chains. It can be widely applied in teaching and research work related to photosynthesis of leaves and algae, stress physiology, selection of high-efficiency varieties, ecological protection, and biological tolerance.
