The SF-3500 Multi-Channel Soil Gas Flux Measurement System is an advanced solution developed by LICA United Technology to address the spatial and temporal variability of soil gas flux. It enables multi-point, long-term, and automatic monitoring of gas fluxes such as CO₂, CH₄, N₂O, and NH₃ across diverse ecosystems. The system can connect to various greenhouse gas analyzers and stable isotope analyzers to perform synchronized multi-parameter flux measurements with high precision. Its robust design, integrated control, and wireless data transmission make it ideal for field research and environmental monitoring in demanding conditions.
Advantages:
- Multi-gas compatibility – supports simultaneous measurement of CO₂, CH₄, N₂O, NH₃, and isotope gases such as ¹³CO₂, ¹²C¹⁸O¹⁶O, and ¹⁵N¹⁴NO.
- Multi-analyzer connection – connects to multiple gas analyzers for synchronous multi-parameter flux analysis, reducing system error.
- Automatic data processing – real-time calculation of gas flux, no need for post-processing.
- Touchscreen and mobile control – LCD display and Android App for full control without a computer.
- Wireless data transmission – remote control and monitoring for easy field operation.
- Durable and field-ready – designed for long-term, stable operation in outdoor conditions.
