依据《工作玻璃浮计》(JJG 42-2011)采用直接比较法,即将标准浮计和工作浮计同时浸入同一检定液中,直接比较它们标尺的示值,从而得到被检工作浮计的示值修正值。此次不确定度评定选择测量范围为650~1500 kg/m3,分度值为0.5 kg/m3的密度计组,测量范围为0%~100%.用分度值为0.2%的酒精计和测量范围为0~40 Bh、分度值为0.1 Bh的波美计作为建立该装置时测量不确定度的评定对象。
依據《工作玻璃浮計》(JJG 42-2011)採用直接比較法,即將標準浮計和工作浮計同時浸入同一檢定液中,直接比較它們標呎的示值,從而得到被檢工作浮計的示值脩正值。此次不確定度評定選擇測量範圍為650~1500 kg/m3,分度值為0.5 kg/m3的密度計組,測量範圍為0%~100%.用分度值為0.2%的酒精計和測量範圍為0~40 Bh、分度值為0.1 Bh的波美計作為建立該裝置時測量不確定度的評定對象。

According to“work glass hydrometers”(JJG 42-2011)using the direct comparison method, the upcoming standard float floating meter gauge and work simultaneously immersed in the same test solution, a direct comparison of their ruler showing the value, resulting in total were seized floating work the value correction value. The Uncertainty Evaluation select measurement range of 650~1 500 kg/m3, indexing is 0.5 kg/m3 density gauge group, the measurement range of 0%to 100%. Use indexing is 0.2%alcohol count and a measurement range of 0~40 Bh, indexing is 0.1 Bh Baume meter measurement uncertainty evaluation to establish the device as an object.
