Conductivity measurement

特許 権利維持 The electrical conductivity of a solution of an electrolyte is measured by determining the resistance of the solution between two flat or cylindrical electrodes separated by a fixed distance.[5] An alternating voltage is used in order to avoid electrolysis. The resistance is measured by a conductivity meter. Typical frequencies used are in the range 1–3 kHz. The dependence on the frequency is usually small,[6] but may become appreciable at very high frequencies, an effect known as the Debye–Falkenhagen effect.
