Multi-point measurement of soil CO2 flux can connect up to 18 respiration chambers, enabling continuous, long-term monitoring of soil carbon flux.
Product Introduction:
LICA's SF-9000 multi-channel fully automated soil carbon flux measurement system can measure soil CO2 flux at multiple points , enabling continuous, long-term monitoring of soil carbon flux. It can connect to up to 18 respiration chambers. The SF-9000 can also be used for CO2 and water vapor profile studies.
Features:
• Control system can connect up to 18 breathing chambers, making it more suitable for experimental designs with multiple repetitions and multiple treatments;
• Long-term field monitoring without human intervention can achieve continuous, high-precision, fully automated unattended monitoring;
• Automatically calculates gas flux, eliminating the need for post-processing.
• Measuring chamber can be connected to auxiliary sensors such as soil temperature and soil moisture.
• Instrument is lightweight and consumes little energy; the entire system is robust and durable.
• Storage medium: SD card
