Main functions: Rapid induction of chlorophyll fluorescence (OJIP), modulation of chlorophyll fluorescence (PAM), pseudo-random binary sequence excitation of fluorescence (PRBS). Emerging AI algorithms are capable of processing complex data containing richer information. In order to leverage the advantages of AI algorithms, Green Vision Core Technology has proposed and implemented a broadband chlorophyll fluorescence excitation method based on PRBS for the first time (patent number: ZL202222096398.6), which enables complex chlorophyll fluorescence data to contain richer plant physiology and stress information, providing basic scientific data for AI algorithm based analysis of multiple plant stresses. The instrument features a capacitive touch screen, real-time visualization of measurement results, USB 2.0 data transmission, 8-hour long battery life (continuous measurement), and supports flexible editable control protocols, timed measurements, and personalized product customization.
