WebMercury porosimetry is used to measure the porosity of a material by applying controlled pressure to a sample immersed in mercury. External pressure is required for mercury to penetrate into the pores of a material due to high contact angle of mercury. The amount of pressure required to intrude into the pores is inversely proportional to the size of the pores. http://gatscientific.com/product/geopyc-1365/ ph test target
