卡尔费休水分测定仪不确定度评定

Evaluation of Uncertainty of Karl Fischer Moisture Analyzer

为了获得卡尔·费休库仑法微量水分测定仪示值误差的不确定度,通过将被校仪器测量值与标准物质标准值两者差值作为卡尔·费休库仑法微量水分测定仪示值误差,依据JJF1059.1-2012《测量不确定度评定与表示》等文献,评定出卡尔·费休库仑法微量水分测定仪示值误差的不确定度。

In order to obtain the uncertainty of the indication error of the Karl Fischer Coulometric trace moisture analyzer,the difference between the measured value of the calibrated instrument and the standard value of the standard substance is used as the indication error of the Karl Fischer Coulometric trace moisture analyzer.According to JJF1059.1-2012"Measurement Uncertainty Evaluation and Representation"and other literature,the uncertainty of the indication error of the Karl Fischer Coulometric trace moisture analyzer was evaluated.
