PMI Gas Pycnometer and Helium Pycnometers by EQBAY True Density and Absolute Volume Analysis

The Porous Materials Inc. Gas Pycnometer and Helium Pycnometers, available through EQBAY authorised dealer, is an advanced laboratory instrument designed for precise determination of true volume and true density of powders, porous materials, and bulk solids. The system operates on the gas displacement principle, where pressure changes within a calibrated chamber are used to calculate the excluded volume of a sample, enabling highly accurate skeletal density measurements. Helium is commonly used as the testing gas due to its ideal gas behavior and ability to penetrate fine surface irregularities, ensuring reliable results even for complex porous structures. The instrument supports fully automated operation with user defined test cycles, allowing flexibility in balancing speed and accuracy. It delivers non destructive testing with high repeatability and is widely used across material science, pharmaceuticals, ceramics, polymers, battery materials, and advanced research applications. With integrated software control, real time data acquisition, and automated reporting, the system ensures consistent and traceable measurement results for quality control and research laboratories.
