Introduction
1.1 Overview
The Teledyne Electronic Technologies Analytical Instruments (TET/AI)
Model 3300TB is a microprocessor-based trace oxygen analyzer for real-time
measurement of the parts per million 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 3300TB 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 0-10ppm
through 9999ppm Large, bright, LED meter readout.
• Simple pushbutton controls.
• Nylon cell holder.
• Advanced Micro-Fuel Cell, for trace analysis, has six months
warranty and an expected lifetime of eight months.
• 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 0-9999 ppm)
allow best match to users process and equipment.
• 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.
• Two concentration alarms with adjustable setpoints.
• Panel mount flowmeter.
• Control valve for the selection of Span gas or Sample gas.
• Sensor failure alarm.
