Advantages
of the LI-820

Drawing on our expertise in developing cutting-edge analyzers for the most demanding research applications, LI‑COR designed the LI‑820 CO2 Analyzer for continuous monitoring applications that require accuracy, durability, and ease of use. The LI‑820 is an absolute, non-dispersive infrared (NDIR) gas analyzer based upon a single path, dual wavelength infrared detection system. This low-maintenance, high-performance monitoring solution gives accurate, stable readings over a wide range of environmental conditions.
