SF-9000 Multi Channel Soil Carbon Flux Automatic Measuring System

Preface:

SF-9000 Multi Channel Soil Carbon Flux Automatic Measuring System（made by LICA, China）could measure soil CO₂ flux at multiple points, realize continuous and long-term monitoring of soil carbon flux, SF-9000 can work with 18 survey chambers. SF-9000 can also be used to study CO₂ and water vapor profiles.

Main features:

u  The control system can connect up to 18 breathing chambers, which is more suitable for the experimental design of multi repetition and multi-processing;

u  Long-term field monitoring without human on duty，can realize continuous、high-precision and automatic unattended monitoring;

u  Automatic calculation of gas flux without post-processing data;

u  Each chamber can be connected with auxiliary sensors such as soil temperature and soil moisture;

u  Light weight and low energy consumption, durable system;

u  Storage medium: SD card
