Conditions
The accuracy specifications above are valid for dry single gases at 22 ± 5 °C and 1013 ± 40
hPa.
☆ Accuracy- All Conditions
The accuracy specification above is valid for all specified environmental conditions except for
interference specified in Section Effects From Water Vapor Partial Pressure On Gas Readings
and Section Interfering Gas Effects.
Effects from Water Vapor Partial Pressure on Gas Readings:
When the breathing gas flows through the sampling line, the gas temperature will adapt to the
ambient temperature before reaching the gas analyzer. The CO
the actual partial pressure at the current humidity level in the gas sample. As the NomoLine
sampling line removes all condensed water, no water will reach NomoLine ISA CO
However at an ambient temperature of 37
the CO reading will typically be 6% lower than corresponding partial pressure after removal of
2
all water.
