“覆膜电极溶解氧测定仪”计量标准重复性试验方法

摘要

The importance of repeatability in measurement standard was introduced. For the measurement standard device which only provided the valve (single-value or multiple-value) that was stable and satisfied a certain uncertainty requirement, its test method of repeatability was discussed. For ‘Dissolved Oxygen Meter with Covered-Membrane-Electrode’, by calculating and analyzing its measurement data, the result shows that actual situation ought to be taken into account, and test method which the most accurately reflect repeatability of measurement standard must be chose to assess repeatability of such measurement standard device.%介绍了重复性在计量标准中的重要作用，针对只提供稳定的、满足一定不确定度要求的量值（单值或多值）计量标准装置，对其重复性的试验方法进行讨论，并以“覆膜电极溶解氧测定仪”为例，对其测量数据进行计算分析，对于此类计量标准装置的重复性进行考核时，应考虑实际情况，选择最确切反映计量标准重复性的试验方法。
