Introduction

1.1 Overview

The Teledyne Analytical Instruments (TAI) Model 3300ZB is a microprocessor-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.

1.2 Main Features of the Analyzer

The main features of the analyzer include:

High resolution, accurate readings of oxygen content from 0-10 parts per million (ppm) through 0-1,000 ppm. Large, bright, light-emitting-diode meter readout

Simple pushbutton controls

Advanced zirconium oxide measuring technology sensors

Fast response and recovery time

Microprocessor based electronics: 8-bit CMOS with on-board RAM and 16 KB ROM

Two user selectable ranges (depending on sensor configuration) allow best match to user’s process and equipment

Operator can select auto-ranging, allowing the analyzer to automatically select the proper preset range for a given measurement or lock the analyzer onto a single range

Two concentration alarms with adjustable set-points

Three analog outputs: two for measurement (0–10 VDC and negative ground 4–20 mADC) and one for range identification (0-10 VDC).
