Product Description
Porosity measurement: Based on Boyle's law (PV equation), the porosity is calculated by measuring the change of gas volume of the core at different pressures; Permeability Measurement: Based on Darcy's law, permeability is calculated by measuring the difference between the flow and pressure of the gas in the core. The instrument also takes into account the effects of the gas slippage effect, which allows for a more accurate calculation of the true permeability of the core
