Although the Analyzer is a rugged instrument, careless handling or abuse may result in
damage to the Analyzer resulting in inaccurate gas analysis. Inaccurate gas analysis can
lead to serious personal injury or death.
Breathing gas must always be analyzed by two separate Analyzers, with one used for
production and one used for analysis after production. Never depend on a single
Analyzer during both gas production and delivery. If the Analyzer readings do not agree,
both units must be recalibrated. Inaccurate gas analysis can lead to serious personal
injury or death.

The Analyzer uses an electrochemical O
is disposable and user-replaceable, with a life expectancy of up to 36 months depending on
usage. The Sensor is designed for use at one atmosphere absolute (0 P.S.I.) pressure. The
gas mixture to be analyzed must be regulated accordingly, and any potential for pressure or
vacuum must be avoided.
To extend sensor life, the Analyzer is supplied with the Sensor in a sealed condition. When first
received, please verify that sealing device is intact. If the sealing device is torn or missing,
contact your supplier for assistance. The sealing device must be removed prior to initial use
and is not necessary to reuse.
