Analyzer
1. Introduction
The EC150 is an in situ, open-path, mid-infrared absorption gas analyzer that
measures the absolute densities of carbon dioxide and water vapor. The EC150
was designed for open-path eddy covariance flux measurements as part of an
open-path eddy covariance measurement system. It is most often used in
conjunction with the CSAT3A sonic anemometer and thermometer, which
measures orthogonal wind components along with sonically determined air
temperature.
Before attempting to assemble, install or use the EC150, please study:
• Section 2, Cautionary Statements
• Section 3, Initial Inspection
• Section 6, Installation
Greater detail is available in the remaining sections.

). Do
not attempt to access or remove these chemical bottles before
reviewing Section 8.5, Replacing CO
2
Scrubber Bottles.
 Avoid direct contact with the chemicals.
 Ensure your work area is well ventilated and free of
reactive compounds and combustible materials.
 Store used chemical bottles in a sealed container until
disposal.
 Dispose of chemicals and bottles properly.
• WARNING:
o Do not carry the EC150 by the arms or the strut between the
arms. Always hold it by the mounting base where the upper and
lower arms connect.
