  • Page 14: Overview

    1. OVERVIEW This instrument measures the concentration of NO, SO , CO , CO and CH contained in sampling gas on the principle that different atomic molecules have an absorption spectrum in the wave band of infrared rays, and the intensity of absorption is determined by the Lambert-Beer law. Since this instrument incorporates a compact O sensor, it allows measuring up to 5 components simulta- neously by using the built-in O...
