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
