Flexible, Reliable Analyzers

We’ve been designing and manufacturing high-speed CO2 and H2O analyzers for more than 30 years. The LI-830 CO2 and LI-850 CO2/H2O analyzers deliver the reliability and flexible configurations that enable simple integration into other products or systems for a variety of applications.

  • Small footprint is ideal for integration
  • 1 ppm RMS signal noise and sampling at 2 Hz
  • Wide measurement range
    • 0-20,000 ppm for CO2
    • 0-60 mmol/mol for H2O
  • Little maintenance required
    • No factory recalibration
    • User-cleanable optical bench
    • Optical source is field-replaceable
  • High and low CO2 or H2O alarm signals
    • Activate LED indicators on the instrument case
    • Activate electronic control signals (TTL or Open Collector)

Fully customizable

The LI-830 CO2 and LI-850 CO2/H2O Analyzers are available in a variety of configurations, with options that include a built-in pump to move sample air streams through the analyzer, and a display for easily viewing real-time measurements. And even if you don’t explicitly require H2O measurements, adding water vapor measurements improves the accuracy of CO2 measurements, by correcting for band broadening due to the presence of water vapor.
