Trace Oxygen Analyzer	Introduction

Introduction

1.1 Overview

The Teledyne Analytical Instruments Model 3000ZA Trace Oxygen Analyzer is a versatile microprocessor-based instrument for detecting oxygen at the parts-per-million (ppm) level in a variety of gases. This manual covers the Model 3000ZA General Purpose flush- panel and/or rack-mount units with CE mark. These units are for indoor use in a non-hazardous environment.

1.2 Typical Applications

A few typical applications of the Model 3000ZA are:

∙Monitoring inert gas blanketing

∙Air separation and liquefaction

∙Chemical reaction monitoring

∙Semiconductor manufacturing

∙Petrochemical process control

∙Quality assurance

∙Gas analysis certification.

1.3Main Features of the Analyzer

The Model 3000ZA Trace Oxygen Analyzer is sophisticated yet simple to use. The main features of the analyzer include:

∙A 2-line alphanumeric display screen, driven by microprocessor electronics that continuously prompts and informs the operator.

∙High resolution, accurate readings of oxygen content for low ppm levels. Large, bright, meter readout.
