Infrared Gas Analyzer

Introduction

1.1 Overview

The Model 7600 Infrared Gas Analyzer is a microprocessor based
infrared gas analyzer used to measure the concentration of NO, SO
CO
, CO and CH
contained in sample gas. It is based on the principle

that different molecular species have unique absorption spectrum in the
infrared, and the intensity of absorption is determined by the Lambert-
Beer law.
In addition to the infrared analyzer, the Model 7600 can also be
equipped with a built-in compact paramagnetic O
external zirconia oxygen sensor to increase to 5 the number of
simultaneous component species the unit can analyze.
Teledyne's Series 7600 Infrared (IR) Gas Analyzer is conveniently
packaged in either a 19" rack mount or NEMA-4 wall mount enclosure.
The NEMA-4 enclosure can be X or Z-purged to satisfy hazardous area
installation requirements.
A high-sensitivity mass flow type twin detector is used for infrared
measurements. By utilizing a single beam, double path design in
conjunction with a serial dual-layer transmission detector, the Series
7600 delivers long term, drift-free performance.
The concentration of the desired gases is displayed on a large, easy-
to-read back-lit LCD. Figure 1-1 shows the standard rack mountable
Model 7600. The user interface is very intuitive and the menu / mode
selection buttons, which are readily accessible, provide the operator with
dynamic control and extensive diagnostic capabilities.
