Introduction

1.1 Overview

The Teledyne Electronic Technologies Analytical Instruments
(TET/AI) Model OT-3 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 OT-3 include monitoring natural gas pipelines, wellheads,
and compressor/blowers.
