Portable photosynthesis analyzer is a core equipment in the field of plant physiology and ecology research, which can measure real-time photosynthesis, transpiration, and related environmental parameters at the leaf level. The instrument adopts non diffusive infrared CO2 analysis technology and multi-sensor fusion design, which can synchronously obtain 15 key physiological indicators, providing accurate data support for plant growth physiology, stress physiology research, and agricultural production optimization.
The importance of portable photosynthesis analyzer
Plant photosynthesis is the fundamental process of energy conversion and material production. Traditional measurement methods have limitations such as complex operation, data lag, and significant environmental interference. The portable photosynthesis analyzer has achieved in situ field measurements of key parameters such as photosynthetic rate (Pn), transpiration rate (Tr), stomatal conductance (Gs), and intercellular CO2 concentration (Ci) through an integrated design, solving the problem of disconnection between laboratory measurements and actual situations, and becoming a "mobile laboratory" for modern plant physiology research.
