Fig. 5.—Side view of the humidifier, showing details of construction. A covered jar of distilled water should be kept in each room for moistening the cloth on the wet bulb of the sling psychrometer. The air temperature of the rooms should be determined from standard- ized thermometers hung in a permanent position in each room. In practice it has been found that the number of humidity deter- minations in the rooms can eventually be greatly reduced. Usually, during ordinary weather, three readings each day will give the necessary information for use in handling the humidifier. With fluctuating weather conditions the readings will of necessity be made more often. It is very desirable to make at least one, prefera- bly more than one, daily determination of the air conditions outside.
