| 摘要 |
The invention relates to a psychrometer (1) having a housing (2) on which a dry thermometer (3) and a moist thermometer (4) are arranged, having at least one temperature scale (10) running along the two thermometers (3, 4) and a movable table (15) assigned to the two thermometers (3, 4), which table (15) has plotted thereon relative air humidity values (24) and is disposed in a conventional manner on the lateral surface of a rotatably mounted shaft (11) disposed in the housing (2), the air humidity values (24) being arranged on the table (15) in the form of a family of curves (K) of equal air humidity with or without numerical values in such a way, that they form air humidity scales (21) which run approximately parallel to the orientation (X-Y) of the capillary tube (27) of the moist thermometer (4) and are assigned to this thermometer (4), there being provided on the roll (11), in addition to the table (15), at least one temperature scale (18, 19) whose individual values each correspond to a particular air humidity scale (21) of the table (15), the dry temperature (Tt), which can be read at the dry thermometer (3), being settable on the temperature scale (18, 19) of the roll (11) by rotating the roll (11) about its axis (12), and thus at the same time the air humidity scale (21) corresponding to said dry temperature (Tt) ... next to the capillary tube (27) of the ...
