Trace Oxygen Analyzer Introduction 1

Introduction

1.1Overview

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.

1.2Main 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.
