The Versatile OXâ„¢ -100
The OXâ„¢ -100 is a durable, battery powered
instrument that accurately measures oxygen
concentration with 0.1% ( 1000 ppm) resolution. Its
rugged construction and compact design enable it to
easily fit into a pocket or toolbox. Supplied with a
protective carrying case, it also attaches to a belt
loop for hands free maneuvering. The OXâ„¢ -100
monitor’ s internal pump draws a sample and its
analyzer quickly provides an easy-to-read digital
LED display. Designed for use in high purity welding
applications in the field, fabrication shop or
construction site; the versatile OXâ„¢ -100 is equally
suited for the production floor, in research labs or for
combustion tuning.
High Purity Welding
The OXâ„¢ -100 is ideally suited for high purity welding
where evacuation of oxygen is paramount. Prior to
welding, the pipe will be pre-purged to displace
oxygen with an inert gas. Constant monitoring of the
oxygen level is necessary until it is ascertained that
the oxygen has been evacuated to 0.1% to enable
the commencement of welding to prevent oxidation,
discoloration and coking. Stainless steel and other
alloys oxidize and discolor in the presence of oxygen.
The purge monitor will measure traces of oxygen,
above 0.1% ( 1, 000 ppm) being exhausted by the
purge gas so that operator knows when a safe level
to begin welding has been achieved. The OXâ„¢ -100
accurately measures low concentrations of oxygen in
purged tubing and high purity weldments, ensuring a
high quality finish.
