1 INTRODUCTION
The Oxor
®
II is a commercial-grade por-
table instrument designed to display con-
centrations of oxygen (O
2
) gas between 0
to 25%. This instrument shows the pres-
ence of O
2
in a gas sample by drawing the
sample into its sensor chamber by a built-
in motorized pump. Part #19-7037 comes
with a probe. Part #19-7044 comes with-
out a probe (All non-probe related func-
tions remain the same in this instruction).
Other features and accessories of the
Oxor II include: A large, back-lit Liquid
Crystal Display (LCD), which allows the
display to be read in any lighting condition
from direct sun-light to total darkness; a
semi-detachable elastic strap that permits
the instrument to be either hand held, or
hung on nearby objects; a rigid stainless
steel probe with sample filter that allows
gas samples to be taken from cramped
and confined areas (alternate probes and
condensate traps may be used).
