FIELD: measuring equipment.
SUBSTANCE: for determining the characteristics of pore volume and thermal conductivity of matrix of samples of porous materials, the sample of porous material is alternately saturated with at least two fluids with different known thermal conductivity. As at least one saturating fluid a mixture of fluids from at least two fluids with different known thermal conductivity is used. After each saturation of the sample the thermal conductivity of the saturated sample of the porous material is measured, and the characteristics of pore volume and thermal conductivity of the matrix of the sample of porous material is determined taking into account the results of thermal conductivity measurements.
EFFECT: increased accuracy and stability of determining the characteristics of the pore volume and the thermal conductivity of the test samples.
