Introduction
The Proox model 360 is a versatile and compact gas oxygen controller for people who
do oxygen sensitive work. Though designed to work with BioSpherix chambers the Proox
360 works in incubators, glove boxes, animal cages, refrigerators, plant growth chambers,
and many other semi-sealable chambers. Pratically any medium-large enclosure can be
fitted.
The unit works from
outside of the host cham-
ber by remotely sensing
and displacing air oxygen
inside the chamber with
another gas. Nitrogen or
an oxygen poor gas, is
used to lower the oxygen
level inside the host
chamber. Oxygen or an
oxygen enriched gas is used to raise the oxygen level
within the host chamber.
Nominal range is 0.1-99.9% oxygen. Advanced
feedback algorithms handle practically any oxygen gas
dynamic. Infusion rates are adjustable up to 350
SCFH. Installation is easy. Operation is simple. The
unit moves easily from one host chamber to another.
Please read and follow the safety and operations
instructions on the following pages. Be careful. Oxy-
gen can be dangerous. Any pressurized gas can be
dangerous. Know what you are doing and do it safely.
