![SF-3500 Multi-Channel Automatic Soil Greenhouse Gas Flux Monitoring System SF-3500 Multi-Channel Automatic Soil Greenhouse Gas Flux Monitoring System]()
Accurate monitoring N2O/CH4/CO2/CO/H2O gas flux in soil
Preface
Soil carbon and nitrogen cycling is an important component of carbon and nitrogen cycling in terrestrial ecosystems, small changes can lead to significant changes in greenhouse gas emissions. There is an antagonistic relationship between the effects of CO2、CH4 and N2O in soil, like a “teeterboard”, in order to reveal the influencing factors and emission mechanism, it is necessary to measure carbon and nitrogen gas exchange simultaneously and accurately.
SF-3500 Multi-Channel Automatic Soil Greenhouse Gas Flux Monitoring System, the latest instrument developed by LICA, it can measure N2O、CH4、CO2、CO and water vapor fluxes in soil at multiple points, help scientists to realize continuous and long-term monitoring of soil carbon flux, as many as 18 chambers can be connected. Meanwhile, SF-3500 can also be used for the study on N2O, CH4, CO2, CO and water vapor profiles.
