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.

 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’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.
