The most compact and lightweight portable photosynthesis analyzer, used to measure parameters related to plant photosynthesis such as photosynthetic rate, transpiration rate, stomatal conductance, etc. of plant leaves. It can be used in research and is also a great teaching instrument. The special design of the Lci portable photosynthesis instrument can be used in high humidity and high dust environments.

Working principle of Lci portable photosynthesis analyzer: Using the IRGA (infrared gas analysis) principle, the parameters related to photosynthesis of leaves and plants are examined based on the precise measurement of changes in CO2 concentration and water content on the surface of leaves.

System composition: Host: Analysis and calculation system and gas circuit; Standard blade chamber: The blade chamber contains an infrared CO2 analysis device and a dual laser tuned fast response water vapor sensor, which can be used to measure various types of blade chamber blade clamps; Power supply system: 12V lead-acid battery and its charger; Desiccant, basic spare parts package, user manual; Software.
