Soil respiration is one of the largest and most important carbon fluxes in terrestrial ecosystems. The spatial variability of soil respiration is obvious due to the soil heterogeneity. Multicompartmental and multiscale monitoring systems will play an important role in soil respiration research. PRI-8600 is a newly designed automated soil gas flux system suitable for long term multipoint soil flux measurment. Comparing with other brands, PRI-8600 has excellent compatibility and extensibility, it’s easy to combine with different analyzers such as various GHGs and trace gas concentration analyzers, various isotope analyzers and other gas measurements devices.
Standard PRI-8600 includes CO2 H2O analyzer and 8/16 channels with dark or clear chambers for soil gas flux or community photosynthesis research, the patented vents of chambers reduce the effects of both internal pressure of chamber and outside wind interference. As option, the patented dual circulation configuration for minimal interference of subsequent chamber, enables low gas flow analyzer to obtain fastest response. Reserved calibration channels supply another option for scientists to calibrate gas isotope online.
PRI-8600 is a rugged, weatherproof mechanical design intergated with sophisticated software, flexible chamber configuration with multiple sensor interface, server-based control unit coupled with web APP. The entire system enables scientists to measure soil flux or community photosynthesis with different gases and isotopes. PRI-8600 can be widely used in ecology, agriculture, forestry, fertilizer, frozen soil, seismology, landfill and sewage treatment.
