Abstract: The present invention relates to a system for measuring physical properties of a dark body which comprises: a core holder unit which includes a core holder in which a dark body core sample is installed; a fluid storing unit which includes a fluid storing container which stores fluid which will be supplied to the core holder unit and a syringe pump which measures total volume (VT) of the fluid which is supplied to the core holder unit in the fluid storing container; a ventilation unit which includes a vent in which fluid of the core holder unit is discharged to outside; a pressure pulse generator which generates pressure pulse added to the core holder unit; a differential pressure measuring unit which measures pressure difference (ΔPD) of both ends of the core holder unit; and an operation unit which calculates total volume (VT) of fluid measured in the syringe pump and porosity and transmittance of the dark body based on the pressure difference (ΔPD) measured in the differential pressure measuring unit. The system for measuring physical properties of low permeable dark body rapidly and accurately measures porosity and transmittance without generating cracks on the dark body by considering low permeability of the dark body.
