Measure carbon monoxide (CO), carbon dioxide (CO<sub>2</sub>), methane (CH<sub>4</sub>) and water (H<sub>2</sub>O)

Measure carbon monoxide (CO), carbon dioxide (CO2), methane (CH4) and water (H2O)

Picarro G2301 and G2401 Analyzers

Simultaneous, precise measurement of CO2, CH4, and H2O for lab, field or mobile applications. Available with or without CO capability.

  • Parts-per-billion sensitivity, precision and accuracy with exceptionally low drift
  • Field and laboratory deployable
  • Installed and operational in minutes
  • Rugged and insensitive to changes in ambient temperature

Measurements of carbon monoxide are important in greenhouse gas monitoring, particularly in partitioning CO2 emissions. These Picarro greenhouse gas instruments enable extremely precise and simultaneous measurements of CO, CO2, CH4 and water vapor at their ambient levels. Both instruments report dry mol fractions of all measured species using Picarro’s unique water corrections, which have been validated by several independent labs. The analyzers can be operated in a remote, unattended monitoring station or used equally well as laboratory reference instruments.
