Oxygen Analyzer

Part II: Analysis Unit

Introduction

1.1

Overview

The Analytical Instruments Model 3010P Analysis Unit is a versatile

remotely controlled instrument for detecting oxygen in a variety of back-
ground gases. Details are recorded in Specifications in the Appendix to this
manual.

Part 1 of this manual covers the Control Unit. Part II, this part, covers

the Model 3010P NEC type explosion proof Analysis Unit only.

1.2

Gas Connector Panel

The standard 3010P Analysis Unit is housed in a NEC type housing

with all gas connections accessible from an external connector panel.
Figure 1-1 is a cutaway illustration of the Analysis Unit showing the Gas
Connector Panel and connectors. The gas connectors are described briefly
here and in detail in the Installation chapter of this manual.
