Teledyne Analytical Instruments

Introduction

1.1

Overview

 The    Teledyne    Analytical      Instruments       Model       3000MA        Percent       Oxygen        Analyzer

is a versatile microprocessor-based instrument for detecting the percentage of
oxygen in a variety of background gases. This manual covers the Model
3000MA General Purpose flush-panel and/or rack-mount units only. These
units are for indoor use in a nonhazardous environment.

1.2

Typical Applications

A few typical applications of the Model 3000MA are:

•

Monitoring inert gas blanketing

•

Air separation and liquefaction

•

Chemical reaction monitoring

•

Semiconductor manufacturing

•

Petrochemical process control

•

Quality assurance

•

Gas analysis certification.

1.3

Main Features of the Analyzer

The Model 3000MA Percent 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 from low
percent levels through 100 %. Large, bright, meter readout.
