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.
