A capillary pressure measurement device includes a centrifuge having a rotating apparatus adapted to hold porous media samples and to test the samples under centrifugal motion during rotation of the rotating apparatus. A fluid capture device disposed adjacent to each porous media sample receives fluid displaced from the sample due to centrifugal motion applied to the sample during rotation. A measurement system measures an amount of fluid displaced from the porous media samples by taking an image of a fluid meniscus in the fluid capture device. A position sensor determines a position of the fluid capture device and triggers a camera to take the image of the fluid meniscus when the fluid meniscus is in a field of view of the camera. The image of the fluid meniscus is processed to determine a fluid volume correlated to capillary pressure of the corresponding porous media sample.
