O Closed-Path Gas
Analyzer
1. Introduction
The EC155 is an in-situ, closed-path, mid-infrared absorption gas analyzer that
measures molar mixing ratios of carbon dioxide and water vapor, along with
sample cell temperature and pressure. The EC155 may be used in conjunction
with the CSAT3 sonic anemometer, which measures orthogonal wind
components.
Before using the EC155, please study
• Section 2, Cautionary Statements
• Section 3, Initial Inspection
• Section 6, Installation
More details are available in the remaining sections.
2. Cautionary Statements
• DANGER:
o The scrubber bottles (see Section 9.5, Replacing the EC155
Desiccant/CO
2
Scrubber Bottles) contain the strong oxidizing
agents sodium hydroxide (caustic soda, NaOH) and anhydrous
magnesium perchlorate (Mg(ClO
4
)
2
).
 Avoid direct contact with the chemicals.
 Ensure your work area is well ventilated and free of
reactive compounds, including liquid water.
 Store used chemical bottles in a sealed container until
disposal.
 Dispose of chemicals and bottles properly.
 Materials Safety Data Sheets (MSDS) are provided in
Appendix D. MSDS are updated periodically by
chemical manufacturers. Obtain current MSDS at
www.campbellsci.com .
• WARNING:
o Do not carry the EC155 or CSAT3A by the arms or carry the
EC155 by the strut between the arms. Always hold them by the
block, where the upper and lower arms connect.
o Handle the EC155 carefully. The optical source may be damaged
by rough handling, especially while the analyzer is powered.
o Over-tightening bolts will damage or deform the mounting
hardware.
