The performance of a method for ionic conductivity measurements in physical gels with use of thermal scanning approach is investigated. It has been shown that this new experimental protocol has several advantages over conventional conductometry with temperature stabilization of the sample. Improved sensitivity of "ongoing" changes, in situ observations of the gel phase and measurements during gelation stage showed interesting features in conductivity and temperature dependences undetectable in conventional conductometry. The comparison of the results for both methods showed very good agreement concerning global features and additional important detail accessible only by the new proposed here method. Ultimately, the method can be used for characterization of the conductivity properties of the system in the gel phase as well as during gelation process, together with detection and validation of the gel-to-sol phase transition temperatures.
