AP-608 Automated Permeameter-Porosimeter (Gas Permeability)


The AP-608 Automated Permeameter-Porosimeter is a cost-effective advanced system for performing automated permeability and porosity tests at confining pressures up to 9950 psi over a wide permeability range. The AP-608 uses a pressure decay technique to determine Klinkenberg-corrected permeabilities, slip and turbulence correction factors.



  • Permeability (Klinkenberg Corrected)
  • Transient, pressure decay permeability measurement (ref. API RP 40)
  • Permeability (air equivalent permeability @ specified mean pressure) 
  • Klinkenberg slip factor "b"
  • Inertial Coefficients (Beta and Alpha)
  • Direct pore volume of core sample
  • Porosity (if bulk volume is known)
  • Compact design for easy maintenance
  • No unnecessary, complicated moving parts that require constant adjustment. The sample loading and unloading is simple and takes only a few seconds
  • Fast porosity and permeability measurements for high-production laboratories
  • USB computer interface
  • Cost is a fraction of what the competition's carousel-based, auto-load system costs 



  • Permeability Range: 0.001 mD to >10 D, depending on sample size
  • Permeability measurement method: Transient / Pressure Decay
  • Pore pressure during permeability measurements: up to 200 psi
  • Porosity Range: 0.1% to >40%
  • Core Sample Size: Length: 0.75 to 4.0 inch
                                   Diameter: 1.5 inch, 1.0 inch and 30 mm
  • Confining Pressure range: 400 to 10,000 psi
  • Easy-loading hydrostatic coreholder
