Description
The Digital Permeability Meter VPD II measures absolute permeability of foundry sand on a standard AFS (2 in x 2 in) or metric (50 mm x 50 mm) specimen. With the relevant attachments it also measures relative permeability of moulds and absolute permeability of cores and unbonded sand. Ethernet (RJ45) output and cloud sync via V-Sync.

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.
