Brit.

/ˌpɒrəʊˈsɪmᵻtə/,

/ˌpɔːrə(ʊ)ˈsɪmᵻtə/, U.S.

/ˌpɔroʊˈsɪmədər/

Origin: Formed within English, by compounding. Etymons: porosity n., -meter comb. form².

Etymology: < porosi- (in porosity n.) + -meter comb. form²; compare -imeter comb. form. Compare earlier (in slightly different sense) porometer n., poroscope n.

Materials Science.

An instrument for measuring the porosity or pore-size distribution of a material.

1922 E. W. Washburn & E. N. Bunting in Jrnl. Amer. Ceramic Soc. 5 116 A special apparatus called a porosimeter has been designed for rapid porosity determinations by the gas expansion method.

1967 Amer. Ceramic Soc. Bull. 46 649/1 The purpose of the present investigation was to test the applicability of a variable pressure mercury porosimeter to a..range of refractory materials.

1993 Amer. Jrnl. Bot. 80 264/1 Porosimeters generate a pressure–volume intrusion curve of a nonwetting fluid as is it forced into the pore space.
