INOSR can estimate the response of root systems and soil microorganisms to climate change by monitoring soil respiration and related parameters. The soil respiration meter can simultaneously display changes in CO2, H2O, temperature, and humidity inside the respiration chamber. It is widely used in agricultural ecological research, carbon source and carbon sink studies, global climate change, land use change, ecological restoration research, soil microbial activity assessment, plant ecology research, insect respiration, root respiration, and fruit storage.
1. Android operating system for more convenient human-machine interaction.
2. 7-inch high-definition touchscreen for simple operation and clear interface.
3. Gas flow can be set via the instrument to conduct experiments on soil respiration intensity at different flow rates.
4. Dedicated dynamic analysis software displays the experimental process in real time on the Android screen, eliminating the need to copy data to a computer for organization and analysis.
