HEP-P Helium porosimeter


The Helium gas expansion porosimeter enables the determination of a sample’s (1” or 1.5” diameter) grain and pore volume via an isothermal helium expansion and the application of Boyle’s law and Charles’ law. Subsequently, porosity and grain density can be calculated. A data acquisition system performs calibration, data logging and parameter calculation. Optionally, a full diameter matrix cup can be provided for porosity studies on whole diameter core samples. Each sample matrix cup is interchangeable and is supplied with stainless steel calibration check plugs. Pore volume can be measured by placing the core sample in an optional Hassler type core holder, connected to the porosimeter.
