PMI Helium Porosimeter by EQBAY Authorised Dealer – Advanced Core Sample Porosity Measurement System

The Porous Materials Inc. Helium Porosimeter, available through EQBAY authorized dealer, is an advanced laboratory system designed for precise determination of effective porosity and grain properties of plug sized core samples. The instrument operates on the fundamental principle of Boyle’s Law, where helium gas is expanded from a calibrated reference volume into a sample chamber to determine pore volume based on stabilized pressure readings. This enables accurate calculation of grain volume, bulk density, and porosity with high repeatability and minimal operator intervention. Helium is used due to its ideal gas behavior and ability to penetrate fine pore structures, ensuring reliable and consistent results even in complex porous materials. The system is available in both manual and fully automated configurations, supporting high speed data acquisition, pressure control, and software driven analysis. It is widely used in petroleum, geoscience, material science, and research laboratories for evaluating rock cores and porous solids with high accuracy and efficiency.
