1.1 General Information

This is a precision equipment used to measure the Permeability of Foundry Sands. By default, it can measure absolute permeability of:
• AFS Specimen (Dia. 2" × 2") • Metric Specimen (Dia. 50mm × 50mm)

With the help of attachments, 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

The specimen held in a tube or accessory is placed over the measuring rubber boss. Upon pressing the start button, the equipment displays permeability readings within seconds.
