一、干湿球湿度计干湿球湿度计也称干湿泡湿度计 ,是最常见的显示当前空气相对湿度的仪器。两支湿度计的准确度应一致 ,一支为干球温度计 ,显示当前的温度 ,一支为湿球温度计 ,其下端感温球上包有纱布 ,纱布浸入盛清水的水槽中。水由于毛细现象上升至感温球 ,水份吸热蒸发 ,湿 First, dry and wet bulb hygrometer Wet and dry bulb hygrometer, also known as wet and dry bubble hygrometer, is the most common display of current relative humidity of the air. The accuracy of the two hygrometers should be the same. One is a dry-bulb thermometer showing the current temperature and the other is a wet-bulb thermometer with a gauze wrapped on the lower temperature-sensing ball. The gauze is immersed in a sink of clean water. The water rises to the temperature-sensing ball due to the capillary phenomenon, and the moisture absorbs heat to evaporate and wet.
