德国化学家恩斯特·奥托·贝克曼发明,因而得名。贝克曼(Beckmann)温度计是精密测量温度差值的温度计,水银球与贮汞槽由均匀的毛细管连通,其中除水银外是真空。刻度尺上的刻度一般只有5℃或6℃,最小刻度为0.01,可以估计到0.002℃。
对原有的贝克曼温度计“标尺读数法”进行了改进,并对新方法作了图解说明。
A visual approach for rapid resettlement of Beckmann thermometer was given in this paper.
介绍一个改进的凝固点下降法测定摩尔质量实验装置,它由保温瓶、凝固点杯、贝克曼温度计、电动搅拌器等几部分构成。
