摘要

TUBITAK UME(土耳其国家计量研究所)电化学实验室于2018年建立了初级电解电导率测量系统。这项工作的目的是在可接受的不确定度下证明所建立系统的准确性,并传播电解电导率测量的可追溯性。在用经认证的电导率溶液测试系统精度的同时,还测试了TUBITAK UME开发的软件的精度。通过使用经认证的电导率溶液,在25°C下确定电池常数为0.57986cm。使用经认证的电导率溶液的测量来评估系统的准确性,发现在95%置信水平下,结果之间没有显著差异。最后,使用“测量数据评估——测量不确定度表达指南”和“EA-4/02M:2013校准测量不确定性评估”指南来形成一级电解电导率测量的不确定度预算。

Primary level electrolytic conductivity measurements at National Metrology Institute of Turkey (TUBITAK UME)
TUBITAK UME (National Metrology Institute of Turkey) Electrochemistry Laboratory established the primary level electrolytic conductivity measurement system in 2018. The objective of this work is to prove the accuracy of the established system with an acceptable uncertainty and to disseminate the traceability for electrolytic conductivity measurements. While the accuracy of the system was tested with the certified conductivity solutions, the accuracy of the software developed at TUBITAK UME was also tested. The cell constant was determined as 0.57986 cm at 25 °C by using certified conductivity solutions. The accuracy of the system was evaluated using the measurement of certified conductivity solutions and it was found that there was no significant difference between the results at 95% confidence level. Finally, “Evaluation of measurement data Guide to the expression of uncertainty in measurement” and “EA-4/02 M: 2013 Evaluation of the Uncertainty of Measurement in Calibration” guides were used to form the uncertainty budget for primary level electrolytic conductivity measurements.
