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.

•Zirconium oxide sensor designed for trace analysis. It has a 0-10 ppm low range with less than a 0.2 ppm
