Five parameter fully automatic soil greenhouse gas flux monitoring system

Accurately monitor soil gas flux: N₂O、CH₄、 CO₂、 CO、H₂O

Soil carbon and nitrogen cycling is an important component of terrestrial ecosystem carbon and nitrogen cycling, and its small changes can cause significant changes in greenhouse gas emissions from ecosystems to the atmosphere. soilCO₂、CH₄andN₂OThere exists a 'seesaw' effect of mutual influence and emission mechanism, which objectively requires simultaneous and accurate measurement of carbon and nitrogen gas exchange.

LICANewly developedSF-3500The fully automatic multi-channel soil carbon flux monitoring system can measure soil at multiple pointsN₂O、CH₄、CO₂、COIt 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 forN₂O、CH₄、CO₂、COResearch on water vapor profiles.

System features:

■Can measure soil from multiple pointsN₂O、CH₄、CO₂、COTo 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;
