Regnault devised a hygrometer of the dew-point type consisting of two silver vessels A and G(see diagram), mounted side by side. Air may be blown from D through a tube C dipping into ether contained in A. This causes the ether to evaporate through E thus cooling the tube A until eventually, at the dew point, moisture condenses on the outside of A giving it a dull appearance compared with the surface of G. This temperature, and that at which the dullness disappears on allowing the apparatus to stand, are noted on the thermometer F, the mean giving the dew point, which in conjunction with the room temperature, enables the relative humidity of the air to be calculated. 1, record 2, English, - Regnault%26rsquo%3Bs%20hygrometer

Hygromètre à condensation. Le plus usité est l'hygromètre d'Alluard. Il se compose d'une boîte en métal dont une face latérale est nickelée, chromée ou dorée extérieurement et encadrée à petite distance d'une plaque de même nature. On envoie un courant d'air dans la boîte, pour provoquer la vaporisation de l'éther que contient celle-ci. La température s'abaisse. Lorsqu'elle devient égale à la température pour laquelle la pression de la vapeur d'eau atmosphérique est maximale, de la vapeur se condense sur la paroi de la boîte, paroi qui devient mate alors que la plaque qui l'encadre reste brillante. 1, record 5, French, - hygrom%C3%A8tre%20d%27Alluard
