PCT No. PCT/GB84/00170 Sec. 371 Date Jan. 17, 1985 Sec. 102(e) Date Jan. 17, 1985 PCT Filed May 17, 1984 PCT Pub. No. WO84/04593 PCT Pub. Date Nov. 22, 1984.A porosimeter comprises a gas supply, a gas pressure regulator for the gas supply, a sample holder having an inlet and an outlet, said inlet being connected to the gas pressure regulator, a gas pressure sensor connected to the gas pressure regulator for measuring the pressure of gas supplied to the sample holder, and a gas flow sensor wherein the gas flow sensor is disposed to measure the gas flow between said gas pressure regulator and said sample holder. Both pressure and flow-rate readings are taken directly from the respective sensors to an automatic recorder which draws mechanically the output in the form of a graph, or may feed them to, for example, an integrating computer.
