This paper presents the relation between the temperature value and the time constant value for the voltammetry
electrode. The problem in voltammetry measurements is the accuracy of the time constant value. Based on mathematical
analysis and laboratory verification, it was shown that it is possible to calculate the time constant of the electrode by
measuring the current. The current must equal to the diffusion limited current value. It was also shown how important in
the voltammetry measurements is the accuracy of the time constant value, because this value determines the dynamic
error of electrode.
