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. More soil flux monitoring sites and bigger monitoring radius enable to reduce uncertainty in soil respiration studies. A newly designed PRI-8600D multiplexer with dual circulation gas flow supplies a good solution for multicompartmental and multiscale monitoring soil flux and net carbon exchange (NCE) research.

PRI-8600D multiplexer is the connection and control center directing the flow of gas between long-term chambers and vrious gas analyzers. Patented dual circulation configuration (ZL201810968150.X) divides plumbing into two groups alternation to work. Build-in calibration channels supply a function to calibrate gas analyzers online.

Key Feature

Two groups plumbing for dual circulation
Build-in three channels for on-line calibration
All-in-one gas and electricity cable assembly
Up to 32 clear and opaque chambers in one box
