Gas-liquid displacement Porometer for the rapid measurement of through-pores in materials such as porous membrane, filters, paper, plastics, thin films, hollow fibers and many other applications.
The POROLUX 1000 measures bubble point, maximum and mean flow pore size, minimum pore size, average pore size distribution of uniform materials and air permeability.
The Porolux 1000 series uses a pressure step method to measure pore diameters. The inlet valve for the gas is a specially designed needle valve that is opened with very accurate and precise movements.The pressure and flow sensors will only take a datapoint when the used defined stability algorithms are met for both pressure and flow. In this way, the Porolux 1000 detects the opening of a pore at a certain pressure and waits until all pores of the same diameter are completely opened before accepting a datapoint. This results in very accurate measurement of pore sizes and allows a calculation of the real pore size distribution.
