Soil respiration measurement system

Instrument Overview：

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, N2O, CH4, temperature and humidity inside the respiration chamber. It is widely used in agricultural ecological research, carbon source and carbon sink research, global climate change, land use change, ecological restoration research, soil microbial activity assessment, plant ecology research, insect respiration, root respiration and fruit storage.

Instrument features:

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

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 can be carried out under different flow rates;

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 100,000+ data;

7. Data can be exported directly to the 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;
