Digital Permeability Meter VPD I

Digital Permeability Meter VPD I


  • 1.1 General information

    This is a precision equipment to measure Permeability of Foundry Sands. By default it can measure absolute permeability of an AFS (Dia. 2”X2”) or Metric (Dia. 50mmX50mm) Specimen.

    With Help of attachment it can also measure

    • Relative Permeability of Moulds (Refer 4.2.1)
    • Absolute Permeability of Cores (Refer 4.2.2)
    • Absolute Permeability of Un-bonded sand (Refer 4.2.3).
  • 1.2 General Usage

    Specimen held in a Tube or accessory is placed on the measuring Rubber Boss. On press of start button, within few seconds the equipment shows Permeability reading.
