Soil respiration testers

1.Overview of Soil Respiration Testers

Soil respiration testers are soil respiration testers who collect and measure gases from soil. They enable on-line, long-term, continuous monitoring of soil CO2 flux.Soil respiration is an important process in the carbon cycle of soil ecosystems. It is the result of the balance of soil carbon assimilation and dissimilation. It is also the main way for carbon to return to the atmosphere from terrestrial ecosystems. It is a representation of life activities in the soil. Accurately measuring its release is the key to evaluating biological processes in ecosystems. By monitoring soil respiration and its related parameters, the response of roots and soil microorganisms to climate change can be estimated. The soil respiration meter can simultaneously display the changes in CO2, H2O, temperature and humidity inside the respiration chamber. It is widely used in agricultural ecological research, carbon source and carbon sink research, global climate change, changes in land use, ecological restoration research, soil microbial activity assessment, plant ecology research, insect respiration, root respiration and fruit storage.

2. Features of Soil respiration testers:

1. Android operating system, more convenient human-computer interaction operation

2. 7-inch high-definition touch screen, simple operation and clear interface;

3. The gas flow rate can be set through the instrument, and the soil respiration intensity test under different flow rates can be carried out;

4. Special dynamic analysis software can display the experimental process in real time on the Android display, eliminating the need to copy data to the computer for sorting and analysis;

5. Support wifi and 4G networking; data can be uploaded to the cloud platform wirelessly; 

6. Storage space 16G, can store more than 100,000 pieces of data;

7. Data can be exported directly to a USB flash drive through the USB interface;

8. After the test is completed, the test data results can be directly printed and uploaded;

9. Support GPS positioning;
