Preface
Irrational greenhouse gas (GHG) emissions from human activities have a significant impact on global climate change. Greenhouse gases mainly includes CO 2 、CH 4 、N 2 O、H 2 O、OCS, etc. Among them, CO 2 、CH 4 and N 2 O 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 CO 2 , CH 4 and N 2 O in the soil significantly increased the gas content of CO 2 , CH 4 and N 2 O 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 PS-3000 portable automatic soil respiration system is a measurement system that utilizes the chamber method to measure soil CO 2 and CH 4 flux emissions. The system has the functions of controlling measurement, storage and data processing. The PS-3000 can read the changes of CO 2, CH 4 and H 2 O in the respiration chamber measured by the ultra-portable greenhouse gas analyzer (MGGA) in real time, and combine the monitoring data of the air temperature, atmospheric pressure and soil temperature. The CO 2 and CH 4 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-11 portable automatic soil respiration chamber can automatically repeat measurements. Also it is light, easy to carry and operate in situ. Uniquely designed, measurement results will be more accurate.
PS-3000 set a variety of measurement parameters through the wireless mobile phone APP real-time, and displays the measurement results of the instrument at the same time.
Main features
l The analyzer could measure CO 2 , CH 4 and H 2 O flux at the same time.
l The analyzer’s measuring frequency could reach 10Hz.
l The system is highly integrated: the controlling system and MGGA analyzer were highly integrated and can be displayed through phone APP.
l Simplified user interface, could easily get the results with only a few operations.
l No need the steps of data post-processing, the measured results can be directly displayed and saved.
l Weight is as light as 5.4 kg.
l The energy consumption is as low as 35W.
