In order to solve the spatiotemporal variability of soil gas flux, LICA has newly developed the SF-3500 multi-channel fully automatic soil gas flux measurement system. SF-3500 can be connected with various gas analyzers and various gaseous stable isotope analyzers to measure soil flux of multiple gases; it can also realize the sequential switching of multiple flux boxes for measurement, and the concentration in the flux box can automatically recover to the background value, so as to conduct long-term and continuous monitoring of multi-point soil gas flux.

In addition, LICA has learned from the advantages of similar products on the market and combined with years of experience to make a lot of improvements. It can connect multiple analyzers, measure multi-parameter flux synchronously, and reduce the system error of multi-system measurement. In addition, LCD touch screen and Android mobile phone APP control and display are added, without computer setting and display. SF-3500 remote control and data transmission functions make instrument maintenance easier and simpler, and more suitable for long-term field measurement. After long-term testing and verification, SF-3500 has better accuracy and stability, suitable for long-term field use.

Can be used in conjunction with various gas analyzers. In addition to CO2, it can also measure gas fluxes such as N2O and CH4, and can also measure 13CO2 isotope gas flux Can connect multiple analyzers at the same time to perform multi-parameter flux synchronous measurement, eliminating multi-system measurement system errors LCD touch screen, Android phone APP control and display, no computer required Automatic calculation of gas flux, no need for post-data processing Remote control and data transmission functions make instrument maintenance easier and simpler, more suitable for long-term field measurements
