Table 5. Gas Types
Gas Type Description
Air Standard room air
N2 100 % Nitrogen
N2O 100 % Nitrous Oxide
CO2 100 % Carbon Dioxide
O2 100 % Oxygen
Ar 100 % Argon
Heliox 21 % Oxygen, and 79 % Helium
O2 bal N2O mix
[1]
Measured Oxygen, balance Nitrous Oxide
O2 bal He mix
[1]
Measured Oxygen, balance Helium
O2 bal N2 mix
[1]
Measured Oxygen, balance Nitrogen
[1]
For these gases, the oxygen concentration is measured using the oxygen sensor in the airflow channel. The balance is the other gas. These
gases can only be measured in the airflow channel, not available in the ultra-low-flow channel of the VT900.
