Measuring carbon monoxide (CO) (NDIR), DIN EN 14626

This document specifies a continuous, non-dispersive infrared photometric measurement method for determining the concentration of carbon monoxide in air. It specifies the performance parameters and sets out the minimum requirements for the suitability testing of non-dispersive infrared photometers. It also covers the assessment of a measuring instrument’s suitability for use at a specific fixed measuring site with regard to the data quality requirements of the EU Directives and the requirements for sampling, calibration and quality assurance.
