How can the accuracy of a Flue Gas Analyzer measuring CO2 be verified?

Verifying the accuracy of a Flue Gas Analyzer measuring CO2 can be effectively achieved by comparing its readings to a known sample. This method ensures that the analyzer is providing accurate measurements by matching them against a standard reference point, which allows for the identification of any discrepancies or calibration errors. Known samples usually consist of gas mixtures with a precise concentration of CO2, and by analyzing these samples with the instrument, technicians can determine if the analyzer is functioning correctly.

This process is critical in ensuring the instrument's reliability, particularly in applications such as combustion analysis where CO2 levels can significantly impact efficiency and emissions. While calibration of the instrument is essential, comparing results against known standards provides a direct method to validate the analyzer’s performance in real-time.
