Complete system used for the determination of resistivity and formation factor of plug sized sample at ambient conditions. The system permits to measure the rock resistivity Ro and the brine resistivity Rw at different frequencies. The cell utilises a two and four electrode design. The platens contact the core end faces under a constant pneumatic pressure up to 6 bar. This minimises contact resistance artefacts which are often found where a screw or jack mechanism is used to load the sample onto the electrode platens. The cell is provided with a plastic cover box to minimise core saturation changes. The instrument also includes a dip conductivity probe and a becher to measure the brine resistivity. An LCR meter is used to monitor the core and brine resistance and capacitance.
