excessively (see Section 9.4 , Zero and Span
(p. 28)
), the bottles should be
replaced. To do this, twist the scrubber-bottle covers of the upper and lower
arms counter-clockwise until they detach (they should loosen by hand).
Remove the IRGASON chemical bottles (pn 26510) from inside the covers,
and replace them with new bottles lid-first (see FIGURE 9-6 ). Once this is
done, firmly screw the covers back on the arms. Allow the sensor to equilibrate
for at least 24 hours (longer if in high humidity), and then perform a zero-and-
span procedure. If readings continue to be suspect, the sensor may need factory
recalibration (see Section 9.6 , Factory Recalibration
(p. 33)
).
The scrubber bottles contain strong oxidizing agents. Avoid
direct contact with the chemicals inside the bottles. Also,
ensure your work area is well ventilated and free of any
reactive compounds, including liquid water. Store used
chemical bottles in a sealed container until disposal.
The chemical bottles should be disposed of according to local and federal
regulations. For more information, MSDS (Material Safety Data Sheets) for the
chemicals are available in Appendix C and at www.campbellsci.com .

9.6 Factory Recalibration
When the IRGASON is manufactured, the gas analyzer calibrated over a wide
range of temperatures, pressures, and gas concentrations. All CO
