Principle 3
The appropriate amount of sample in a vacuum degassing station, then filled with mercury seepage material carried by a high pressure system dipped, immersed in mercury
Volume according to the pressure applied to the recording. External pressure, the smaller the pore radius of mercury can enter Different measuring external pressure mercury into the hole
To know the amount of pore volume and average pore diameter of the corresponding hole.
