PRI-8400 Underground Online Dilution Profile Continuous Measurement System
Share This Page :

Soil respiration is one of the largest and most important carbon fluxes in terrestrial ecosystems. Surface flux research can not discover entire soil biochemistry processes. Undergrand gas reaserch will help us understand better on soil gas migration and soil biochemistry processes. PRI-8400 is a newly designed automated underground soil gas profile pretreatmet system, it’s easy to connect with low measurement range analyzers, suitable for long term multilevel soil flux measurments.

Standard PRI-8400 includes 6 sampling channels with simi-permeable membrane gas exchange module, and online dilution module, 3 channels calibration module as option. Innovative simi-permeable membrane design can minimize sampling error caused by soil heterogeneity. Scientific and sophisticated gas exchange module also minimizes sampling interference within the soil. As option, the patented dual circulation and CO2 pretreatment module for minimal interference of subsequent level soil, enables scientists to obtain more accurate data.

PRI-8400 is a rugged, weatherproof mechanical design intergated with online dilution module, which can be used for various soil research. The system can be widely used in the fields of ecology, agriculture, forestry, fertilizer, permafrost, plant rhizosphere physiology and ecology.

Key Feature

  • Innovative membrane gas exchange technology
  • large dynamic online dilution
  • No disturb on soil internal gas circulation metabolism
  • Continuous sampling and minimal interference
