1.0 System Description
The Nuvair Analyzer Trio measures Oxygen (O
2
), Carbon Dioxide (CO
2
), and Carbon Monoxide
(CO) levels in supplied gases. All Analyzers are in a water resistant, impact resistant case with
a clear cover that allows for viewing of all gas displays, visual alarms and easy access to
analyzer controls. This unit is compatible with outdoor and marine environments.
The internal sensors are plumbed together to monitor a single input. Pressurized gases must be
regulated down to atmospheric pressure to avoid damage to the analyzer. The sample flow
rate must be between 1.0 to 5.0 L/min for an accurate reading.
The Analyzer Trio has visual and optional audible alarms for each of the gases monitored. An
audible alarm will sound if any alarm set point is reached.
All analyzers must be calibrated with an appropriate certified calibration gas before operation.
Battery powered units will come equipped with a Lithium battery and dedicated charger. The
Lithium battery charger may also be used as a constant power source. If the user chooses to
use the charger as a power source for an extended period, it is recommended that the Lithium
battery be disconnected from the analyzers to avoid battery damage.
This analyzer is designed for use at atmospheric pressures only. It is not designed for
exposures in a hyperbaric chamber. Use of this analyzer in a hyperbaric chamber will
result in incorrect readings and may damage the unit.
Although the Analyzer is a rugged instrument, careless handling or abuse may result
in damage to the Analyzer components resulting in inaccurate gas analysis. Inaccurate
gas analysis can lead to serious personal injury or death.
Extreme Gas exposure levels directed at the Analyzer sensors may damage the
sensors.
