【Abstract】 The working principle, construction and characteristics of an infrared gas analyzer are described. The signals are processed and controlled by an 8096 single chip computer. The display, measurement, calibration and output are set or altered through keyboard. The stability and anti interference ability of the analyzer are considerably improved by using detectors with front and rear gas chambers, related software and phase sensitive rectifying circuit.更多还原
