Double-pass flue gas analyzer |
摘要 |
A mixture of H2O, CO2 and CO are measured in the same sample chamber by infrared radiation passing through the chamber and absorption filters passing a narrow band in their respective absorption curves to an infrared detector. Background radiation is zeroed by grounding the detector response when an opaque segment is disposed in the path. A reference filter detects drift which is automatically corrected.
