The present invention is a device and method for measuring sample resistivity. The sample is a kind of cement-based material. The said device includes a transformer comprising a priamry coil and a secondary coil made of the sample to be measured, a unit to provide voltage to the priamry coil, and a unit to measure the induced voltage in the sample. The resistance of the sample is measured, and then the resistivity of the concrete sample is calculated. |
