In this paper, the aim has been to construct equipment capable of measuring the superconductivity of materials. This is done by investing the resistivity and susceptibility of superconductors. When a superconductor is cooled down below its critical temperature, its resistance will drop to zero and the magnetism of it will change from paramagnetism to perfect diamagnetism. The change in resistance and magnetic susceptibility as a function of temperature is to be measured for high temperature superconductors of the BSCCO family. The set-up has been successfully constructed except for a few parts to be created externally. Unfortunately, due to these missing parts, it was not possible to test the equipment's capabilities on the samples of the superconductors.
