    • To provide a hygrometer and a dew-point instrument that can be structurally simplified while reducing the workload of their maintenance. The hygrometer is a hygrometer for measuring a relative humidity of a measurement space, and has: a main body part that is configured to encapsulate a working fluid therein and to cause a heat-pipe phenomenon and is disposed across the measurement space and an external space that is spaced from the measurement space by a heat-insulating part and has a temperature lower than that of the measurement space; first temperature deriving means for deriving the temperature of the main body part in a section where the working fluid evaporates; a space temperature detecting unit for detecting the temperature of the measurement space; and a computation unit for calculating the relative humidity of the measurement space based on the temperature of the main body part derived by the first temperature deriving means and the temperature of the measurement space detected by the space temperature detecting unit.
    • 提供湿度计和露点仪,可以在结构上简化,同时减少维护工作量。 湿度计是用于测量测量空间的相对湿度的湿度计,并具有:主体部分,其被构造成将工作流体封装在其中并且引起热管现象并且被布置成横跨测量空间和外部空间 通过绝热部与测量空间隔开且温度低于测量空间的温度; 第一温度导出装置,用于导出在工作流体蒸发的部分中的主体部分的温度; 空间温度检测单元,用于检测测量空间的温度; 以及计算单元,用于基于由第一温度导出装置导出的主体部分的温度和由空间温度检测单元检测的测量空间的温度来计算测量空间的相对湿度。
