1.1 Introduction
The Teledyne Analytical Instruments (TAI) Model 3110XL
Portable Oxygen Analyzer is a portable, intrinsically safe oxygen
analyzer capable of analyzing oxygen levels from 0-2 parts per million
(ppm) oxygen to 25% oxygen (dependent on configuration). These units
are rated as intrinsically safe and may be used in a Class I, Div 1, Group
A-D hazardous environment. The instrument operates from internal
rechargeable batteries and is supplied with a universal AC charge
adapter. It features quick-disconnect fittings for sample connections and
a rugged, lightweight housing with handle. This versatile instrument can
be brought to the sample site and set up for analysis quickly and easily.
Because of the intrinsically safe design, the instrument can be employed
even in hazardous environments without compromise once calibrated.
The Model 3110XL incorporates a large standard feature list designed
for versatile, accurate oxygen analysis for a wide range of applications.
Figure 1-1 shows the standard Model 3110XL Portable Trace Oxygen
Analyzer.
The microprocessor based Model 3110XL instrument provides one
user settable analysis range at trace sensitivities. The single user-defined
range can be set anywhere from 0-2 ppm to 0-25% oxygen.
Sample oxygen is displayed on a 2-line 20 character alphanumeric
LCD display mounted on the front panel. Four buttons are used to
interface with the instrument and access all of the analyzer features.
Sample gas is introduced and vented via a pair of quick-disconnect
fittings that feature integral shutoff valves which automatically close
when the mating male fitting is withdrawn. The fittings are an integral
part of the measuring cell manifold so that internal sample passage
volume is at an absolute minimum.
