INTRODUCTION
1 INTRODUCTION
The XZR400 Series Trace Oxygen Analyzer is designed to measure oxygen as an inpurity
in nitrogen, carbon dioxide, argon, helium or other inert gases. Analysis is both quick
and stable, utilizing our metallic sealed reference sensor (MSRS), with no requirement
for reference air.
There are 4 versions of the XZR400 analyzer. All are trace oxygen analyzers designed to
measure oxygen content in gas, between 0.01 ppm and 25% O
2
(250,000 ppm).
Michell Instruments can supply the analyzer so that it is suitable for use with enriched
oxygen samples, including pure oxygen which may accidentally be introduced to the
sample. This cleaning service must be ordered at the time of purchase as special
components are required.
Extended operating ranges of 0 to 30% or 0 to 50% O
2
can be supplied but will require
the analyzer to be cleaned for oxygen service.
Typical applications include:
Gas purity
Inerting or blanketing speci
fi
c atmospheres
Combustion pre-mixing analysis
Respiratory or medical gas mixtures
Heat treatment
Four models of the XZR400 Series Oxygen Analyzer are available:
• A rack-mount model XZR400A1 (XZR-400-RM)
• A wall-mount model XZR400A2 (XZR-400-WM)
• A bench-mount model XZR400A3 (XZR-400-BM)
• A transportable model XZR400A4 (XZR-400-TP)
NOTE: The rack-mount version can be supplied with a built-in Easidew
sensor for measuring moisture in the range -100 to +20 °C
Sample gases at pressures up to a maximum of 2 barg (29 psig) can be accepted.
