Measures N2O and CO

The Picarro PI5310 gas concentration analyzer is designed for high-precision measurements of nitrous oxide (N2O) and carbon monoxide (CO). Precisely measuring these naturally occurring greenhouse gases (GHGs) is critical to understanding the nitrogen cycle and in atmospheric studies related to climate change. The PI5310’s mid-infrared (IR) Cavity Ring-Down Spectroscopy (CRDS) produces parts-per-trillion (ppt) measurements of N2O  and CO over a 1 to 1,500 parts-per-billion (ppb) measurement range at less than 5 second intervals. Drift is less than 0.1 ppb, for infrequent analyzer calibration and maintenance. The PI5310 is ideal for long-term atmospheric measurements required by the most demanding greenhouse gas monitoring networks.

  • Simultaneous and continuous measurement of N2O and CO
  • Excellent long-term stability and low drift
  • Measure H2O vapor and report dry mole fractions
  • Outstanding pressure and temperature stability
  • Meet the requirements of the WMO GHG compatibility goals and ICOS atmospheric stations specifications


The PI5310 is built on the latest Picarro chassis and Linux operating system and includes features to enhance its robustness and ease of use.
