Abstract

A more accurate method of measuring the electrical conductivity (L) of solutions was developed by applying dynamic temperature compensation for measurement of L. Temperature changes of a sample were induced by a heater probe and the changes in L per unit temperature were measured. An equation for L with respect to temperature change was developed and L at the standard temperature ($25^{\circ}C$) was computed. Based on our proposed method, it is possible to have temperature compensation without having the temperature coefficients in advance.
