Percent Oxygen Analyzer Introduction 1
Teledyne Analytical Instruments
Introduction1.1 Overview
The Teledyne Electronic Technologies Analytical Instruments (TETAI)
Model 3300PA is a microprocessor-based percent oxygen analyzer for real-
time measurement of the percent of oxygen in inert gases, or in a wide variety of
gas mixtures. It features simple operation, fast response, and a compact, rugged
construction. Typical applications of the Model 3300PA are monitoring nitrogen
generators and inert gas blanketing applications.
1.2 Main Features of the Analyzer
The main features of the analyzer include:
•High resolution, accurate readings of oxygen content from 0-1 %
through 0-25 %, with 0-100% range optional. Large, bright, light-
emitting-diode meter readout.
•Simple pushbutton controls.
•Nylon cell holder.
•Advanced Micro-Fuel Cell, for percent analysis, has a two year
warranty and an expected lifetime of 3 years.
•Unaffected by oxidizable gases.
•Fast response and recovery time.
•Microprocessor based electronics: 8-bit CMOS microprocessor
with on-board RAM and 16 KB ROM.
•Two user selectable ranges (from 0-1 % through 0-25 %) allow best
match to users process and equipment.
•Air-calibration range for convenient spanning at 20.9 %.
