Key Features:

  • Wide Measurement Range: 0-20,000 ppm for CO2, 0-60 mmol/mol For H2O.
  • Wide Operating Temperature: -20° to +45°C
  • Low Power: Less than 4W after power up
  • Low Noise: Less than 1 ppm @ 370 ppm for CO2, less than 0.01 mmol/mol at 10 mmol/mol for H2O with 1 second signal averaging.
  • Real Time Corrected Readings: On board sensors measure and correct for changes in cell temperature and pressure. CO2 concentrations are corrected for band broadening due to water vapor.
  • User Cleanable Optics: The optical bench can be easily cleaned by the user; which reduces down-time due to contamination, and eliminates the need for factory recalibration.
