16. Enter the known dew point (in C°) in the box labeled Span Dew Point and

press Span.

17. The zero-and-span procedure is now complete. Remove the shroud,

reconnect the IRGASON temperature probe, and prepare the site for

normal operation.

9.5 Replacing Desiccant and Scrubber Bottles

If more than two years have passed since replacing the desiccant / scrubber

bottles within the IRGASON, or if the zero-and-span readings have drifted

excessively (see Section 9.4, Zero and Span), 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 (p/n 26510) from inside the covers, and replace

them with new bottles lid-first (see Figure 9-5). 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).

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.

DANGER

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.
