threeWorking principle
Electrical resistivity is an important indicator of carbon products. It is related to the energy consumption of aluminum production and other performance of the product. To determine the resistivity of carbon materials, the voltammetry method is generally used. A stable direct current is passed through a fixed sample with a certain cross-sectional area, and the resistivity of the sample is calculated by measuring the voltage drop between two probes.
