SF-3500 Series Multi-channel Soil Gas Flux Measurement System

From

To address the spatio temporal variability of soil gas flux, LICA has developed a new multi-channel, automatic soil gas flux measurement system, the SF-3500.The SF-3500 can be connected to various green house gas analyzer sand stable isotope analyzers to measure the fluxes of multiple gases in soil. It can also enable the sequential switching of multiple flux chambers for measurement, allowing for long-term and continuous monitoring of multi-point soil gas flux. It can connect numerous analyzers to measure multi-parameter flux synchronously, thereby reducing the system error associated with multi-system measurements. In addition, an LCD touch screen and an Android mobile phone app are added for control and display, eliminating the need for computer settings and a separate display. The SF-3500 remote control and data transmission functions make in strument maintenance easier and simpler, making it more suitable for long-term field measurements. After long-term testing and verification, the SF-3500 demonstrates improved accuracy and stability, making it an ideal choice for prolonged field use.

Features

  • It can be used in conjunction with various gas analyzers. In addition to CO2, it can also measure gas fluxes such as N2O, CH4, and NH3, as well as isotope gas fluxes like 13CO2, 12C18O16O, and 15N14NO.
  • It can simultaneously connect multiple types of analyzers to perform multi-parameter flux synchronous measurements, thereby eliminating errors in multi-system measurement systems.
  • LCD touch screen, Android mobile phone APP control and display, no computer required.
  • Automatically calculate gas flux, no need for post-data processing.
  • Remote control and data transmission functions make instrument maintenance easier and simpler, and more suitable for long-term field measurements.
