Features and Benefits

• Simultaneous measurements of OCS (or COS), CO₂, CO, and H₂O

• Fast response allows flux measurements

• 0.1-ppm CO₂ precision in only 10 seconds (better precision with increased averaging)

• H2O measured simultaneously and used to report values on dry mol basis accurately in real time (without post processing)

• Cryogen-free operation

• Installed in minutes

• High-resolution absorption spectra always viewable

• Linear over extremely wide ranges
