LI-820 CO2 Gas Analyzer: Ideal For
Continuous CO2 Monitoring Applications

The LI-820 CO2 Analyzer is a low cost, low maintenance CO2 analyzer designed for continuous monitoring applications.  It is an absolute, non-dispersive infrared (NDIR) gas analyzer based upon a single path, dual wavelength, infrared detection system. It can be used in a wide range of environmental conditions.

The optical benches can be easily cleaned by the user; simply remove the source and detector headers and swab out the optical path (a cleaning kit is included with the LI-820). This reduces down-time due to contamination, and eliminates the need for factory recalibration.
