Whenever a precise measurement is required
 Ideally, the calibration should be performed at a temperature approximating that of
the experiment planned and in a moderately humid atmosphere (50 to 70% RH).
In practice, the ambient conditions of a laboratory or classroom are sufficient for a
satisfactory calibration.
 It should be noted that the level of CO
increase by 0.3% by the end of the period. It is therefore best to perform the
calibration in a well-ventilated room.
