The rock electrical resistivity measuring instrument is widely used to determine the resistivity values of rock cores at different water saturation levels, and the relationship curve between saturation and resistivity index is automatically drawn by computer software based on the changes in the measured values. The water saturation and resistivity index of the core are automatically collected and calculated by the computer.

The equipment can achieve saturation testing of rock cores under different conditions and changes in resistivity parameters under corresponding conditions by adjusting temperature and pressure, in order to guide practical operations.
