CONSIDERATIONS ON THE ACCURACY OF MEASUREMENTS OF ELECTRICAL CONDUCTIVITY OF LIQUIDS

Zbigniew Moron

Abstract

The purpose of this paper is the presentation of new requirements created by contemporary applications of electrolytic conductivity measurements, the main factors limiting accuracy of such measurements and also discussion of the means enabling minimization of effects caused by these factors. Recently observed demand for accurate microscale conductivity measurements, mainly in biomedical engineering, involves new features required from the conductivity sensors and co-operating electronics: miniaturization, robustness, low price (mass produced, disposable devices). Consequently, a new approach in designing such instrumentation is required.
