Portable photosynthetic efficiency meter

The FluoMini EFF portable plant photosynthetic efficiency meter can quickly and accurately measure the photosynthetic efficiency of plants. Using innovative fiber optic sensors from Sendot in the Netherlands, accurate measurements can be made by simply installing the blade clamp on the blade. This photosynthetic efficiency meter has a recording function and can be continuously measured for several weeks in the field or indoors. At the same time, it is equipped with a photosynthetically active radiation (PAR) sensor, which can simultaneously measure the photosynthetic efficiency and PAR intensity of the same part of the leaves, providing decision-making basis for researchers and crop growers to choose a suitable planting environment.

Application cases

Case 1: Measurement comparison with Li COR 6400 portable photosynthetic instrument

At present, the LI-6400 photosynthetic instrument from Li COR company is the most commonly used in the field of plant photosynthesis research; We conducted experimental comparisons with it; The measurement results were found to be very close; Moreover, the patterns of the measured environmental changes are highly consistent, which fully demonstrates the accuracy of the FluoMini EFF plant photosynthetic efficiency instrument; In addition, the FluoMini EFF plant photosynthetic efficiency meter has higher portability and ease of operation, as well as good cost-effectiveness. It can also perform simple diurnal changes in photosynthesis measurement and even continuous weeks of uninterrupted photosynthesis measurement, making it more applicable.
