Part II: 1-1

Oxygen Analyzer

Part II: Analysis Unit

Introduction

1.1

Overview

The Analytical Instruments Model 3010T Analysis Unit is a versatile

remotely controlled instrument for detecting trace amounts of oxygen
(0-10 ppm to 0-250 ppm) in a variety of background 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 3010T NEC type explosion proof Analysis Unit only.

1.2

Gas Connector Panel

The standard 3010T 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.

•

Flowmeter

Monitors the flow of gas past the sensor.
Readout is 0.2 to 2.4 standard liters per minute
(SLPM).

•

ZERO IN

(On –C Option only) Zero gas inlet. Internally
valved. Controlled by Control Unit via Remote
Probe connector.

•

SAMPLE IN

Sample gas inlet. Controlled (with –C option)
by Control Unit via Remote Probe connector.

•

SPAN IN

(On –C Option only) Span gas inlet. Internally
valved. Controlled by Control Unit via Remote
Probe connector.

•

EXHAUST

Exhaust gas outlet.
