HOW TO MEASURE ELECTROLYTIC CONDUCTIVITY SUCCESSFULLY

Zbigniew Moroń, Tomasz Grysiński

Abstract

Measurement of electrical conductivity of liquids (electrolytic conductivity), despite of its apparent easiness, can cause serious problems – especially when is performed in conditions different from those defined by the manufacturer of the conductivity meter applied or when an instrument of own design is used. The purpose of this paper is to present the most substantial and most frequent problems that may occur in such measurements and how to master them. Effective remedial measures were indicated.

Keywords
