Three parameter fully automatic soil greenhouse gas flux monitoring system

Accurately monitor soilCH₄，CO₂ andH₂OGas flux

Excessive greenhouse gas emissions can cause changes in the atmospheric environment, such as global warming, and also lead to an increase in pests and diseases on Earth, which not only endangers the balance of natural ecosystems but also poses a greater threat to human food supply and living environment. Among greenhouse gases, the one with a larger proportion isCO₂The stronger greenhouse effect isCH4Therefore, it is necessary for us to analyze and predict these two gases, clarify their hazards and development trends, and control them early.

LICANewly developedSF-3500The three parameter fully automatic multi-channel soil carbon flux monitoring system can measure soil at multiple pointsCH₄、CO₂ It can be connected to water vapor flux up to18A breathing chamber for continuous and long-term monitoring of soil carbon flux. In addition,SF-3500It can also be used forCH₄、CO₂Research on water vapor profiles.

System features:

■Can measure soil from multiple pointsCH₄、CO₂To achieve continuous and long-term monitoring of soil carbon flux in conjunction with water vapor flux;

■The control system can connect up to18A breathing chamber is more suitable for experimental designs with multiple repetitions and treatments;

■It can achieve fully automatic, high-precision, unmanned, and continuous long-term monitoring in the field;

■Automatically calculate gas flux without the need for post-processing data;

■Each breathing chamber can be connected to auxiliary sensors such as soil temperature and soil moisture;

■The instrument is lightweight, energy-efficient, and the system is sturdy and durable;
