    • How it works

    The PSP32 system utilizes advanced pulse-modulated fluorescence technology and automated probes to measure key plant physiological parameters.

    It automatically adjusts for daylight and dark-adapted conditions, accurately evaluating chlorophyll fluorescence metrics such as FV/FM, quantum yield (Y(II)), and electron transport rate (ETR).

    With customizable scripts and advanced quenching analysis capabilities, the system provides insightful and automated long-term stress monitoring, seamlessly operating in laboratory, greenhouse, or remote field locations.

    Applications

    • Comprehensive stress monitoring in agricultural research
    • Ecological and environmental stress assessments
    • Photosynthesis research
    • Greenhouse and growth chamber experiments
    • Crop physiology and breeding programs

    Key features
