摘要
阐述了如何正确使用pH(酸度)计测量邻苯二甲酸氢钾pH标准溶液,并依据JJF 1343-2012《标准物质定值的通用原则及统计学原理》建立数学模型,建立了邻苯二甲酸氢钾pH标准溶液定值不确定度的评定程序和评定方法.
Abstract
This article explains how to correctly use a pH(acidity)meter to measure the pH standard solution of potassium hydrogen phthalate,and establishes a mathematical model based on JJF 1343-2012 General Principles and Statistical Principles for Determining the Value of Standard Substances.It also establishes an evaluation procedure and method for the uncertainty of the pH standard solution of potassium hydrogen phthalate.
