Accuracy standard conditions
The following accuracy specifications are valid with no drift for dry single gases at 22 ± 5 °C and 1013 ± 40 hPa:
Range
0 to15 vol%
CO2
N2O 0 to 100 vol%
0 to 8 vol%
HAL, ENF, ISO
SEV 0 to 10 vol%
DES 0 to 22 vol%
O2 0 to 100 vol%
Accuracy - all conditions
The following accuracy specifications are valid with no drift for all specified environmental conditions, except for
interference from water vapor in the below section "Effects from water vapor partial pressure on gas readings".
GAS Accuracy
CO2 ±(0.3 kPa + 4% of reading)
N2O ±(2 kPa + 5% of reading)

Agents ±(0.2 kPa + 10% of reading)
O2 ±(2 kPa + 2% of reading)
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 measurement of all gases will always show the actual partial pressure at the current humidity
level in the gas sample. As the NOMO section removes all condensed water, no water will reach the ISA gas analyzer.
However at an ambient temperature of 37 °C and a breathing gas with a relative humidity of 95% the gas reading will
typically be 6% lower than corresponding partial pressure after removal of all water.

All gas concentrations are reported in units of volume percent and may be translated into mmHg or kPa by using the reported
atmospheric pressure.

The accuracy specification is not valid if more than two agents are present in the gas mixture. If more than two agents
are present, an alarm will be set.
