Analyzer
CAUTION
To reduce the effects of humidity on the Sensor:
• DO NOT USE the Oxygen Sensor in environments with greater
than 95% humidity.
• Place the Oxygen Sensor upstream from the Humidifier in a
breathing circuit.
EFFECTS OF PRESSURE:
CAUTION
The Oxygen Analyzer is not equipped with automatic barometric
pressure compensation.
The following recommendation is provided to reduce the chances of
pressure causing false readings.
Calibrate the Precision Medical Oxygen Analyzer using 100% oxygen
or room air at the same pressure and flow as the gas to be analyzed.
