Introduction
1.1 Overview
The Teledyne Analytical Instruments (TAI) Model 3290 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 3290
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 %. Large, bright, light-emitting-diode (LED) meter
readout.
 Simple pushbutton controls.
 Nylon cell holder.
 Advanced E-2 oxygen sensor for percent analysis, has a two-year
warranty on the standard cell and an expected lifetime of four
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 %,
optional 0-100%) allow best match to user’s process and
equipment.
 Air-calibration range for convenient spanning at 20.9 %.
