Abstract: This article presents the stages of development of a non-dispersive infrared (NDIR) open-type gas analyzer prototype (NGAP-1) with a fundamentally new discrete IR radiation generation scheme using pulse-width modulation for measuring the dynamics of water vapor and carbon dioxide concentrations, with further application in the instrument base of an ecological and climatic station to implement the eddy covariance (EC) method. In addition, selecting the component base for NGAP-1, as well as its calibration and experimental field validation as part of an ecological and climatic station, are described.
