PRI-8620 is a new generation portable soil flux system, which includes CO₂ CH₄ H₂O senor and portable soil flux Chamber. Onboard temperature and pressure sensors enable real-time environmental condition measurements thus providing true concentration readings and reliable measurement of the target gases in a wide range of locations. Patented pressure balance unit (ZL201420354126.4) minimize wind influence, enable scientists to get more accuracy soil flux data.

       PRI-8620 is a rugged mechanical design intergated with sophisticated software, flexible chamber configuration with multiple sensor interface, smart control unit coupled with web APP. The entire system enables scientists to measure soil flux or community photosynthesis with different gases.

• Portable soil flux system for both CO₂ and CH₄
• Manual chamber or automatic chamber options
• Patented pressure vent minimizes soil disturbance and pressure perturbation
