Overview

       The device uses the Bolyer's law to determine porosity, using the known volume of standard body and under the set initial pressure to expand the gas to the core chamber under normal pressure to expand into the core pore.The effective pore volume and particle volume of the rock sample are obtained by using the change of pressure and the known volume and according to the equation of gas,and then calculate the porosity.
