Four parameter fully automatic soil gas flux monitoring system

Accurately monitor soilNH₃、CH₄、CO₂ andH₂OGas flux

Ammonia is an important alkaline gas and nitrogen-containing sedimentary compound in the atmosphere,Not only can it directly harm ecosystems at high concentrations, but it can also participate in the formation of fine particles that affect atmospheric visibility and precipitationpHAfter settlement, it can lead to eutrophication of water bodies and soil acid-base imbalance. Methane is a greenhouse gas that has a significant impact on the energy balance of the Earth's gas system and the conversion of atmospheric components,China's greenhouse gas emissions are among the highest in the world,It is urgent to accurately determine the pollution situation and control greenhouse gas emissions.

LICANewly developedSF-3500The four parameter fully automatic multi-channel soil carbon flux monitoring system can measure soil at multiple pointsNH₃、CH₄、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 forNH₃、CH₄、CO₂ Research on water vapor profiles.

System features:

■Can measure soil from multiple pointsNH₃、CH₄、CO₂ To 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;

■Storage medium:SDcard
