Six parameter fully automatic soil gas flux monitoring system

Accurately monitor soilNH₃、CH₄、CO₂、H₂O、N₂O、COGas flux

Ammonia is an important alkaline gas and nitrogen-containing sedimentary compound in the atmosphere,Not only can it directly harm ecosystems at high concentrations, but it can also participate in the formation of fine particles that affect atmospheric visibility and precipitationpHAfter settlement, it can lead to eutrophication of water bodies and soil acid-base imbalance. Methane is a greenhouse gas that has a significant impact on the energy balance of the Earth's gas system and the conversion of atmospheric components,China's greenhouse gas emissions are among the highest in the world,It is urgent to accurately determine the pollution situation and control greenhouse gas emissions.

In the soil,N₂OIt is produced by nitrifying and denitrifying microorganisms, and excessive nitrogen fertilizer is applied to farmland to promote microbial activity. Through the process of nitrification and denitrification, nitrogen is converted intoN₂O.N₂OLong lasting in the atmosphere, it can be transported to the stratosphere, leading to the destruction of the ozone layer, causing the ozone hole, and exposing humans and other organisms to the radiation of ultraviolet rays from the sun, causing damage to the human skin, eyes, and immune system.

Among various atmospheric pollutants emitted by industryCOMainly, pollutants will fall into the soil with precipitation and natural sedimentation, reducing the potential for land production and deteriorating product quality, causing serious harm to humans, animals, and plants.

LICANewly developedSF-3500The multi-channel fully automatic soil carbon flux monitoring system can measure soil at multiple pointsNH₃，CH₄，CO₂，H₂O，N₂O，COContinuous and long-term monitoring of soil carbon flux can be achieved through water vapor flux, which can be connected to up to18A breathing room.SF-3500It can also be used forNH₃，CH₄，CO₂，H₂O，N₂O，COResearch on water vapor profiles.
