Zero air and span gas are required for accurate calibration.
A gas that is similar in chemical composition to the earth's atmosphere but without the
gas being measured by the analyzer, in this case SO
an Internal Zero Span (IZS) or an external zero air scrubber option, it is capable of
creating zero air.
For analyzers without an IZS or external zero air scrubber option, a zero air generator
such as the Teledyne Model 701 can be used (Figure 3-16).

measured at near full scale of the desired measurement range. In this case, SO
