device for adjustment to a standard #01670
Adjustment using a dry gas is possible provided that the difference of effect between wet and dry gases is known or can be automatically corrected. (*) This ± 1 °C tolerance does not correspond to the uncertainty when preparing calibration gases (which is usually of 0.1 °C); it is the tolerance on the nominal temperature of calibration gases in use.

ID: 01670
a device for adjusting the EBA using, as a standard, a mixture of gases having a relative humidity of at least 90 % and a temperature of 34 °C ± 1 °C(*). The mixture of air and ethanol passes through the entire gas analysis train, starting with the mouthpiece, in the direction normally taken by exhaled air
