Trace Oxygen Analyzer Introduction 1
Teledyne Analytical Instruments
Introduction1.1 Overview
The Teledyne Analytical Instruments (TAI) Model 3190 is a micropro-
cessor-based trace oxygen analyzer for real-time measurement of trace
amounts 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 3190 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
0-10 ppm through 0-25 %. Large, bright, light-emitting-diode
meter readout.
•Simple pushbutton controls.
•Nylon cell holder.
•Advanced Micro-Fuel Cell, for trace analysis, has a six (6)
months warranty and expected lifetime.
•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 0-10 ppm through
0-9,999 ppm) allow best match to users process and equipment.
•Air-calibration range for convenient spanning at 20.9 %.
•Operator can select Autoranging, which allows the analyzer to
automatically select the proper preset range for a given
measurement, or he can lock the analyzer onto a single range.
