Portable Photosynthesis analyzer​ Product introduction:
The HLY-GH4 portable photosynthesis analyzer is our company's new model, which can not only analyze plant photosynthesis, but also detect soil respiration. HLY-GH4 adopts two measurement methods, open circuit measurement and closed circuit measurement, mainly analyzing the changes in CO2 concentration, air temperature, leaf temperature, air humidity, leaf chamber humidity, photosynthetically active radiation intensity and other factors during photosynthesis in plants, in order to calculate the plant's photosynthetic rate, transpiration rate, intercellular CO2 concentration, stomatal conductance, water use efficiency and other indicators. When conducting soil respiration testing, the breathing chamber is installed in the soil, and the gas in the soil is sucked into the analysis chamber through an air pump to accurately measure the CO2 content released from the soil. By measuring soil respiration and related parameters, the response of roots and soil microorganisms to climate change can be evaluated. The HLY-GH4 photosynthesis analyzer is suitable for research experiments in various fields such as biology, agriculture, horticulture, forestry, insects, microbiology, ecology, etc.
