Complete Eddy Covariance Systems

LI-7500RSOpen Path CO2/H2O Analyzer

  • In-situ measurements
  • Temperature regulated optical filters for long term stability
  • Onboard data logging of complete eddy covariance datasets
  • Fast and precise CO2 and H2O measurements
  • Improved optics increase stability in dusty conditions

LI-7200RS Enclosed CO2/H2O Analyzer

  • Short intake tube optimized for flux measurements
  • Outputs CO2/H2O mixing ratio to simplify flux calculations
  • Onboard data logging of complete eddy covariance datasets
  • Flow Module for a controlled flow rate
  • Preferred for environments with frequent rainfall, fog, or snow
  • Improved optics increase stability in dusty conditions

LI-7700 Open Path CH4 Analyzer

  • Draws nominally 8W of power
  • Data output rate up to 40 Hz
  • Simplified methane flux calculations in EddyPro™ software
  • Monitors signal strength and actively cleans lower mirror when signal decreases below a user-defined limit
  • No pumps, no tubing sorption, and no tubing delays
