Infrared Gas Analyzer Introduction Introduction 1.1 Overview The Model 7600 Infrared Gas Analyzer is a microprocessor based infrared gas analyzer used to measure the concentration of NO, SO , 2 CO , CO and CH contained in sample gas. It is based on the principle 2 4 that different molecular species have unique absorption spectrum in the infrared, and the intensity of absorption is determined by the Lambert- Beer law. In addition to the infrared analyzer, the Model 7600 can also be e
