A reliable and precise estimate of the temperature sensitivity (Q₁₀) of soil organic matter (SOM) decomposition is critical to predict feedbacks between the global carbon cycle and climate change.

       Traditional methods for estimating Q₁₀ includes CDM mode (constant temperature incubation and discontinuous measurements) and VDM mode (varying temperature incubation and discontinuous measurements). According the conclusion of Robinson（2017），no less than 20 temperature points could get more precision Q₁₀. Which is difficult for traditional measurement. Combining rapidly VCM mode (varying temperature incubations and continuous measurements), PRI-8800 (patented) leads a new method for Q₁₀ estimation. VCM mode eliminates the underestimated errors by both CDM and VDM modes, provide a more accurate and rapid estimation of the temperature response of SOM decomposition and can be used for large-scale estimation of Q₁₀.

       PRI-8800 is a new and exciting solution for continuous soil respiration measurements combining varying temperature incubations in lab. Excellent compatibility and extensibility with other analyzers such as various GHGs and trace gas concentration analyzers, various isotope analyzers and other gas measurements devices. Applications are related to soil respiration, biodegradability of plastics in solid medium, biodegradability of plastics in aqueous medium, organic waste (solid or liquid samples), food industry, compost biological activity, wastewaters, R&D in biotechnology, biology, ecology and pharmacy.
