The POROMETERS 3G micro, 3G macro, 3Gz and 3Gzh are latest generation capillary flow porometers. Using the technique known as liquid expulsion, they measure pore size distributions and other related information of through-pores. In this technique, an increasing pressure is applied to one side of a wetted porous sample while pressure and flow rate are monitored. As the pressure is increased, the pores in the sample are progressively emptied (largest through-pore first, then smaller ones). The flow rate through the emptied pores is recorded and used together with the pressure to provide information such as the maximum pore size, the mean flow pore size and full pore size distributions.



The 3G porometers can also generate gas permeability information from the pressure and flow rate data.

The Porometer 3G series provides exceptional performance in compact desk top units. They are equally appropriate for material science testing labs, research and development and quality control departments.
