The Model XLE 302/112 CO2 Analyzer is economical, reliable and easy to use. The analyzer uses the proven non-dispersive (NDIR) principle to detect and monitor the presence of CO2. By incorporating two internal active detectors and a reference detector with an infrared source and specific filtering, the carbon dioxide concentrations can be determined. The operator is provided a continuous measurement of the CO2 concentrations.
The infrared sensor typically lasts 3 years. The sensor assembly can be easily replaced in the field.
Calibration is fast and simple. One bottle of CO2 and one bottle of Nitrogen is required. (See the VIDEOS tab and watch “How to Calibrate CO2 Process Analyzer.)
