摘要： A porosimeter evaluates the porosity characteristics (specifically, pore volume, pore distribution and liquid permeability) of a porous sample of material. The porosimeter includes a fluid reservoir located below the sample, and a penetrometer comprising a vessel which catches any fluid displaced from the reservoir of fluid, wherein a level of fluid rises in the penetrometer when additional fluid enters the penetrometer. The sample is preferably wetted, with the same type of fluid which is in the reservoir, prior to placing the sample on the porosimeter. The porosimeter preferably also includes a membrane located between the sample and the reservoir of fluid. The membrane has pores with a size smaller than any of the sample pores. Permeability is measured by measuring rate of flow while the liquid level is above the sample.
摘要翻译：孔隙度计评估多孔材料样品的孔隙特性（具体地，孔体积，孔分布和液体渗透性）。孔隙率计包括位于样品下方的流体储存器，以及透明计，其包括捕获从流体储存器移位的任何流体的容器，其中当附加流体进入渗透计时，渗透计的水平升高。在将样品置于孔隙率计上之前，样品优选用与储存器中相同类型的流体润湿。孔隙率计优选地还包括位于样品和流体储存器之间的膜。膜具有尺寸小于任何样品孔的孔。当液面高于样品时，通过测量流量来测量渗透性。

摘要： A sample chamber includes a movable upper chamber. The movable upper chamber includes a center bore opening to a bottom of the chamber, at least one port for introduction of gas under pressure to the center bore, and a first annular seal around the center bore. A stationary lower seat opposing the upper chamber has a center bore aligned with the upper chamber. and includes an exhaust and a second annular seal around the center bore. A test material is placed between the upper chamber and the lower seat. An actuator moves the upper chamber. When the upper chamber is moved down with the first annular seal in contact with an upper surface of a sample of the material and the second annular seal in contact with a lower surface of the sample, gas introduced to the upper chamber goes through the upper chamber and out through the exhaust.
