Multi-Channel Automatic Soil Carbon Flux Measurement System

Description:

GSF-9000 Multi-Channel Automatic Soil Carbon Flux Measurement System can measure soil CO2 flux at multiple points for continuous, long-term soil carbon flux monitoring, and can be connected to up to 18 respiration chambers.

GSF-9000 can also be used for CO2 and water vapor profiling studies.

Features:

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

* Long-term field monitoring, no human duty, can achieve continuous, high-precision, automatic unattended monitoring;

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

* Each measuring chamber can be connected to auxiliary sensors such as soil temperature and soil moisture;

* Light weight, low energy consumption; The whole system is robust;

* Storage media: SD card.
