HYGROMETER: Instrument for measuring humidity. This means the % ratio between the absolute and the maximum humidity. If the temperature rises, the relative humidity will fall if the absolute humidity remains the same. Inside the hygrometer, use is made of the property of hairs, which expand when water is absorbed and contract when water is released. In modern instruments, a plastic tissue with the same properties is also used for this purpose. By combining a hygrometer with a thermometer, whereby the two pointers cross, a "climate meter" is created with which the dew point can be determined.
