A process of conditioning gases for measurement of transmission of a first gas into a second gas, comprising the steps of: passing a portion of said first gas into a vertical column having water and beads therein through the bottom thereof; passing said portion of said first gas vertically upward within a conduit through the height of said column and subsequently passing said portion of said first gas vertically downwardly within a passageway through said column; wherein said conduit is within said passageway and said passageway is within said column having water and beads, said passageway substantially surrounded by said water; thereby equilibrating the temperatures of said first gas and said water; directly contacting said portion of said first gas with the water in said column whereby said portion of said first gas passes through said water and said beads to the top of said column; removing said portion of said first gas from said column by passing said portion of said first gas downwardly through another conduit through said column and out the bottom thereof; combining said removed said portion of said first gas with the remaining portion of said first gas in a controlled manner so as to form a mixed first gas of a controlled humidity; passing a portion of said second gas into a second vertical column having water and beads therein through the bottom thereof; passing said portion of said second gas vertically upward within a conduit through the height of said second column and subsequently passing said portion of said second gas vertically downwardly within a passageway through said second column; wherein said conduit is within said passageway and said passageway is within said column having water and beads with said passageway substantially surrounded by said water; thereby equilibrating the temperature of said second gas and said water; directly contacting said portion of said second gas with the water in said second column whereby said portion of said second gas passes through said water and said beads to the top of said second column; removing said portion of said second gas from said second column by passing said portion of said second gas downwardly through another conduit through said second column and out the bottom thereof; combining said removed portion of said second gas with the remaining portion of said second gas in a controlled manner so as to form a mixed second gas of a controlled humidity; passing said first and second gas mixtures to means for measuring the transmission of one of said gases into the other of said gases.
