Which analyzer is used to measure carbon monoxide, carbon dioxide, and oxygen?

The Orsat analyzer is specifically designed to measure the concentrations of carbon monoxide, carbon dioxide, and oxygen in various gases, particularly in combustion processes or flue gas analysis. It operates on the principle of gas absorption, utilizing chemical reagents to determine the percentage of these gases present in a sample.

The effectiveness of the Orsat analyzer lies in its ability to provide accurate readings of these critical gases, which is essential for monitoring air quality, optimizing combustion effectiveness, and ensuring compliance with environmental regulations. Understanding the levels of carbon monoxide, carbon dioxide, and oxygen is vital for assessing combustion efficiency and air pollution control.

Other options, such as the TSS transducer (which is typically used for measuring total suspended solids in liquids), the Rankin monitor (not a standard term in gas analysis), and a rheostat (a device used for adjusting resistance in electrical circuits), do not pertain to the analysis of gaseous components mentioned in the question. Thus, they are not suitable for this specific purpose.
