Zero air is a gas that is similar in chemical composition to the earth's atmosphere but
scrubbed of all components that might affect the analyzer's readings, in this case CO
and water vapor. If your analyzer is equipped with an Internal Zero Span (IZS) or an
external zero air scrubber option, it is capable of creating zero air.
