Note regarding the analyzers performance characteristics
The performance characteristics of the analyzers have been determined according to IEC 61207-1:2010 “Expression of performance of gas analyzers – Part 1: General”. They are based on operation at atmospheric pressure (1013 hPa) and nitrogen as the
associated gas. Compliance with these characteristics when
measuring other gas mixtures can only be assured if their composition is known. The physical detection limit is the lower limit
of the performance characteristics relative to the measuring
range span.
