Nitrogen meters are special instruments that measure the concentration of atomic nitrogen (N2) in units of volume of atmospheric air. Used to determine the level of air pollution from industrial emissions. Thus, a nitrogen analyzer is an analyzer capable of measuring and producing results in units of the volume fraction of oxygen or nitrogen, prescribed in the technical specifications. Since the N2 molecule under normal conditions consists of one nitrogen atom and two oxygen atoms, the volumetric content of N2 is the sum of the concentrations of nitrogen and oxygen. Considering such a large importance of the oxygen component (many hundreds of times greater than all other gases of the atmosphere), it is generally accepted to consider this mixture as an inert gas contained in the inhaled air, which reacts little with other components of the atmosphere. The main elements included in
