Electrolytic conductivity at DFM - results and experiences

摘要

DFM has built a primary standard for electrolytic conductivity. The standard is based on the concept of a removable center section, and achieves traceability through the calibration of the geometric parameters of the center section, and through traceable measurement of impedance. This article describes the standard, the measurement procedures, and the results and experiences gained through the work with the standard. Finally, the future directions for our work are given.
