Soil Respiration Measurement System

Instrument Introduction:

The soil respiration measurement system can display real-time changes in CO ₂, H ₂ O, N ₂ O, CH ₄, temperature, and atmospheric pressure inside the respiration chamber. It is widely used in agricultural ecological research, carbon source and sink research, global climate change, land use change, ecological restoration, soil microbial activity assessment, plant ecology research, insect and root respiration research, and fruit storage.

Soil respiration is an important process of carbon cycling in soil ecosystems, which is the result of the balance between carbon assimilation and assimilation. It is also the main pathway for carbon return to the atmosphere in terrestrial ecosystems, reflecting the life activities in the soil. Accurately measuring its release is key to evaluating ecosystem biological processes. By monitoring soil respiration and related parameters, the response of roots and soil microorganisms to climate change can be estimated.

Instrument features:

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

2. 7-inch high-definition touch screen, easy to operate and clear interface;

3. Not only can it measure the release amount of N ₂ O and CH ₄, but it can also display their release rate;

4. The gas flow rate can be set by the instrument, and experiments on soil respiration intensity can be conducted at different flow rates;

5. Specialized dynamic analysis software that can display the experimental process in real-time on Android screens, eliminating the need to copy data to the computer and organize analysis;

6. ★ Supports WiFi and 4G networking; Data can be wirelessly uploaded to the cloud platform;

7. Storage space of 16GB, capable of storing over 100000 pieces of data;

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

9. After the detection is completed, the detection data results can be directly printed and uploaded;

10. Supports GPS positioning.
