Soil respiration is a crucial process in the carbon cycle of soil ecosystems, resulting from the balance between soil carbon assimilation and dissimilation, and is also a major pathway for carbon to return to the atmosphere from terrestrial ecosystems. It is a characteristic of soil life activities, and accurately measuring its release is key to evaluating ecosystem biological processes. By monitoring soil respiration and its related parameters, the responses of roots and soil microorganisms to climate change can be assessed. Soil CO₂ flux is influenced by a variety of complex spatiotemporal physical and biological processes; therefore, long-term, continuous, and accurate measurement of soil carbon flux is of great significance for studying carbon flux in terrestrial ecosystems. Soil respiration meters can simultaneously display CO₂ concentration, temperature, and humidity changes within the respiration chamber, as well as the intensity of external photosynthetically active radiation. They are widely used in agricultural ecology research, carbon source and sink research, global climate change, land use change, ecological restoration research, soil microbial activity assessment, plant ecology research, insect respiration, and root respiration.
Features:
1.Simultaneous detection of multiple parameters, including CO₂, temperature, humidity, photosynthetically active radiation, and airflow;
2.High-specification core sensors ensure accurate and sensitive detection, with CO₂ difference data acquisition in 1 second;
3.Strong environmental adaptability, resistant to -20~60℃ and 0-85% humidity, suitable for routine testing;
4.Long battery life (12 hours with lithium battery) and large storage (2GB expandable to 16GB), suitable for field operations;
5.Easy to operate, true-color screen visible even in strong light, direct data transfer via USB, compact and portable main unit;
6.Wide range of applications, suitable for ecological and carbon sequestration research, as well as insect/root respiration detection.
