The LI-COR LI-7810 CH4/CO2/H2O Trace Gas Analyzer provides exceptionally stable and precise methane measurements in a design that is both portable and affordable.
About
LI-COR Trace Gas Analyzers use laser-based spectroscopy to measure gases in air with high precision and accuracy. Optical Feedback-Cavity Enhanced Absorption Spectroscopy (OF-CEAS), in combination with numerous patented innovations,1 has resulted in an exceptionally stable gas measurement platform that features a small form factor and low power requirements. Combining these features, LI-COR Trace Gas Analyzers can serve the needs of a variety of research applications, including long-term atmospheric monitoring, climatology studies, mobile monitoring, soil gas flux measurements, and more. The compact form factor, low power requirements, and light weight make the instruments ideal for laboratory and field work alike.
