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.
