Features:

Versatile: Simultaneous determination of photosynthetic rate, transpiration rate, intercellular carbon dioxide concentration, stomatal conductance and water use efficiency, as well as carbon dioxide concentration, relative humidity, photosynthetically active radiation and air temperature, and blade temperature

Stability: A temperature-tuned dual-wavelength infrared carbon dioxide analyzer is added, and the carbon dioxide measurement accuracy is not affected by temperature changes. The air pump flow can be set as needed to measure the effect on photosynthesis under different gas flows, and the gas flow is stable.

Intelligent: multi-information Chinese menu display and cursor-guided operation, instantly display and store the measurement process and final result screen

Small size, light weight, carry-on, single operation

Wide range of applications: with different types of leaf chambers (breathing reactors) can be widely used in the determination of different shapes of leaves of various crops such as field crops, fruit trees, vegetables, forest trees, pastures, and respiration of soil, seeds, insects, etc.

High cost performance: low price, low cost of use, easy maintenance
