Renewed interest in soil science has occurred with recognition that biogeochemical processes influence global climate change, land degradation and remediation, the fate and transport of nutrients and contaminants, food sufficiency and safety, and other issues related to the management of land resources. Soil respirometry (O2, CO2, CH4 measurement) is used to aid characterization of the soil condition.

Salient Features

  • Highest resolution, variable flow through or constant volume respirometry
  • Rugged and compact systems for field use
  • Benchtop systems offer automated acquisition with multiple chambers
  • Broad range, high stability CO2 measurement
  • Highest-resolution water vapor pressure/ RH / Dewpoint analyzer
  • Expandable to include Methane analysis
