摘要
以具体实例分别介绍了以二等标准水银温度计和二等标准铂电阻为标准器校准标准恒温槽的方法,对两种方法进行了比较,并对不同的方法作了不确定度评定:以二等标准水银温度计为标准器在100℃时的扩展不确定度为0.08℃,以二等标准铂电阻温度计为标准器在100℃是的扩展不确定度为0.026℃。
This article introduced two methods on the measurement of thermostatic bath, standard mercury-in-glass thermometer （GradeⅡ ） and standard platinum resistance thermometer （ Grade Ⅱ ）. At the same time, the evaluation of measurement uncertainty was completed. The results were as follows： the expanded uncertainty was 0.08℃ with standard mercury-in-glass thermometer （ Grade Ⅱ ）, and the expanded uncertainty was 0.026℃ with standard platinum resistance thermometer （ Grade Ⅱ）.
