The SF-9000 Multi-Channel Soil Carbon Flux Automatic Measurement System, developed by LICA United Technology, is a high-performance instrument designed for multi-point, long-term, and automatic monitoring of soil CO₂ flux. It enables precise quantification of carbon exchanges between the soil and atmosphere, providing valuable insights into soil respiration, ecosystem carbon balance, and environmental change. The system supports up to 18 soil chambers operating simultaneously and automatically calculates gas flux without any post-processing, ensuring continuous and unattended operation for extended field campaigns.
Advantages:
- Multi-channel architecture – supports up to 18 soil chambers for simultaneous monitoring across multiple sites.
- Automatic operation – long-term and unattended monitoring with built-in data processing.
- Accurate CO₂ and H₂O measurement using non-dispersive infrared absorption (NDIR) technology.
- High-capacity data logging with SD card storage and multiple communication interfaces.
- Integrated 5-inch LCD touchscreen for easy setup and real-time visualization.
- Energy-efficient and durable design, suitable for continuous outdoor operation.
- Optional environmental sensors for soil temperature, humidity, and barometric pressure measurement.
