PRI-8602 Smart Backpack for Soil Flux
Share This Page :
PRI-8602 Smart Backpack is a portable, self-powered soil flux system to assess the spatial variability of soil gas fluxes. Connectivity is up to three analyzers through RS-232 port and computes real-time fluxes based on either manual chamber or automatic chamber.  
PRI-8602 is a sophisticated hub for various analyzers, compatible with both traditional NDIR sensor and new-generation laser multi-gas analyzer. Onboard pressure sensors enable real-time environmental condition measurements thus providing true concentration readings and reliable measurement of the target gases in a wide range of locations. Patented pressure vent (ZL201420354126.4) minimize wind influence, enable scientists to get more accuracy soil flux data.  

Key Feather
  • Sophisticated hub for various analzyer to mesuare soil flux
  • Self-powered with long-lasting batteries
  • Patented pressure vent minimizes soil disturbance and pressure perturbation
  • Built-in sampling circular line with progressive multihole for uniform sampling
