A hygrometer and dew-point instrument is provided that is structurally simple while reducing the workload during maintenance. The hygrometer measures relative humidity of a measurement space, and has a main body that encapsulates a working fluid therein and causes a heat-pipe phenomenon. The main body is disposed across the measurement space and an external space spaced from the measurement space by a heat-insulating part and has a temperature lower than the measurement space. A first temperature deriving part derives the temperature of the main body in a section where the working fluid evaporates. A space temperature detecting unit detects the temperature of the measurement space. A computation unit calculate relative humidity of the measurement space based on the temperature of the main body derived by the first temperature deriving part and the temperature of the measurement space detected by the space temperature detecting unit.

ENVIRONMENT TESTING APPARATUS CAPABLE OF CONTROLLING CONDENSATION AMOUNT, AND CONTROL METHOD THEREFOR
Provided is an environment testing apparatus with which it is possible to obtain stable condensation conditions at the surface of a test object, with the changes in condensation amount being smaller than in the past. The environment testing apparatus (100) includes a regulator (4). On the basis of a signal from a condensation amount sensor (9), the regulator (4) maintains the temperature of a cooling/heating plate (6) between the wet-bulb temperature obtained from a wet bulb (11), plus deviation, and the dew-point temperature inside a test chamber (1), plus deviation.
A second tank for accommodating a sample is disposed within a first tank. A heater for heating gas is provided inside the second tank. A heater controller controls the heater such that temperature of gas becomes a set temperature. A heat conducting member is disposed such that one end of the heat conducting member is positioned in the gas inside the first or second tank and the other end is positioned in the humidifying water contained in the humidifier. The heat conducting member is made of material having higher thermal conductivity than that of gas inside the first or second tank.
Dehumidification efficiency is enhanced at a dehumidifying section while reducing the driving power. The humidity control equipment comprises a section for humidifying the air, and a section for dehumidifying the air and humidity control of a humidity control space is carried out by these humidifying section and dehumidifying section. The dehumidifying section has a body section arranged to be filled with working fluid and to create heat pipe phenomenon, a heat insulating portion being fitted over the body section, and a heat absorbing section for condensing the gas state working fluid evaporated in the distal portion becoming the other side for the heat insulating portion of the body section by absorbing heat from the proximal portion becoming one side for the heat insulating portion of the body section. The air is dehumidified at the distal portion of the body section where the liquid state working fluid evaporates.
