Product Name: PS-3010 Automatic Soil CO2/CH4 Flux System

Portable survey measurement system 

PS-3010  Automatic Soil CO2/CH4  Flux System


Irrational greenhouse gas (GHG) emissions from human activities have a significant impact on global climate change. Greenhouse gases mainly includes CO2 CH4 N2OH2OOCS, etc. Among them, CO2 CH4 and N2O are considered to be main GHG and has been widespread concerned. Soil greenhouse gas respiration is an important flow path in the global greenhouse gas cycle. The loss of CO2, CH4 and N2O in the soil significantly increased the gas content of CO2, CH4 and N2O in the atmosphere and enhanced greenhouse gas effects. On-line, long-term and accurate measurement of soil greenhouse gas flux, which are of great significance to the study of greenhouse gas flux.


The Automatic soil CO2/CH4 Flux system is a portable survey measurement system that utilizes the chamber method to measure soil CO2 and CH4 flux emissions. The system includes ABB LGR gas analyzers, PS-3010 control unit and SC-12 soil Survey Chamber.


PS-3010 control unit has the function of control, data storage, and data analysis, and it can set a variety of measurement parameters through the wireless cell phone APP in real-time and display the measurement results of the instrument at the same time. PS-3010 can read the changes of CO2, CH4 and H2O in the survey chamber measured by the Microportable greenhouse gas analyzer (MGGA) in real time, and combine the monitoring data of the air temperature, atmospheric pressure and soil temperature. The CO2 and CH4 emission flux values are then can be obtained. Meantime the acquired raw data and the calculated flux results are stored in the SD card.


SC-12 soil survey chamber can automatically repeat measurements. It is controlled by PS-3010. And it is light, easy to carry and operate in situ. Uniquely designed, measurement results will be more accurate.



Main features


u  The analyzer could measure CO2, CH4 and H2O flux at the same time.

u  The analyzer’s measuring frequency could reach 10Hz.

u  The system is highly integrated: the control system and MGGA analyzer were highly integrated and can be displayed through phone APP.

u  Simplified user interface, could easily get the results with only a few operations.

u  No need the steps of data post-processing, the measured results can be directly displayed and saved.

u  The energy consumption is as low as 35 W.
