EC150 CO

O Open-Path Gas

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.

2. Cautionary Statements

• DANGER:

o The scrubber bottles in the EC150 contain sodium hydroxide

(NaOH) and anhydrous magnesium perchlorate (Mg(ClO

)

). Do

not attempt to access or remove these chemical bottles before

reviewing Section 8.5, Replacing CO

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.
