SF-9000 Multi-Channel Soil Carbon Flux Automatic Measurement System

The SF-9000 Multi-Channel Soil Carbon Flux Automatic Measuring System, manufactured by LICA in China, is capable of measuring soil CO2 flux at various locations, enabling continuous and long-term monitoring of soil carbon flux. The SF-9000 can operate with up to 18 soil chambers and is also suitable for studying CO2 and water vapor profiles. 

Main features:

The control system supports the connection of up to 18 soil chambers, making it ideal for experimental designs that require multiple repetitions and processes.

It allows for long-term field monitoring without the need for human supervision, facilitating continuous, high-precision, and automatic unattended monitoring.

The system automatically calculates gas flux without the need for post-processing of data. Each chamber can be equipped with additional sensors, such as those for measuring soil temperature and moisture.

The system is lightweight, energy-efficient, and built for durability.

The storage medium utilized is an SD card.
