Automated Gas Permeameter

Automated Gas Permeameter

The Automated Gas Permeameter is designed to measure the permeability of core specimens 1.5" in diameter and up to 4" in length. The core specimen is placed into a quick access core holder with a stationary core boot. Confining pressure constrains the core inside the boot while gas flows through it. Dual auto-switching mass flowmeters measure the flowrate of the gas through the core. The software controls the confining pressure and inlet pressure on the core while calculating the permeability.


  • Measures permeability of a core sample
  • Quick access core holder with stationary boot makes loading and unloading the core sample quick and easy
  • Dual auto-switching mass flowmeters provide greater accuracy over the measurement range
  • Software controls confining pressure and gas inlet pressure while calculating and recording permeability over time
