  使用时,应将干湿计放置距地面1.2~1.5米的高处。读出干、湿两球所指示的温度差,由该湿度计所附的对照表就可查出当时空气的相对湿度。因为湿球所包之纱布水分蒸发的快慢,不仅和当时空气的相对湿度有关,还和空气的流通速度有关。所以干湿球温度计所附的对照表只适用于指定的风速,不能任意应用。例如,设干泡温度计所示的温度是22℃,湿泡温度计所指示的是16℃,两泡的温度差是6℃,可先在表中所示温度一行找到22℃,又在温度一行找到6℃,再把22℃横向与6℃竖行对齐,找到数值54。它的意思就是相对湿度是54%。

 

 

 

【用途】: 广泛应用于可用于家居、办公室、酒店、实验室、幼儿园、养殖业,仪器仪表车间,图书馆,中小学校,工厂车间等环境测量 ;
