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 interchangeable 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.

Using the 5 cm optical bench shown, CO2 ranges to 20,000 ppm are possible.
