Abstract. An optical-electronic gas analyzed is developed on the base of optical absorption spectroscopy method for measurement of nitrogen dioxide concentration in motor vehicle emission. Technical characteristics of radiation source and detectors used in the analyzer are outlined; optical scheme of the instrument is presented. Advantages of the new detector over the classical one are described.
