Permmeter Instrument Information
A device which test the permeability (the ease of gases passing through) of sand used in the foundry industry. The device contains a place for air to be supplied, a three-way valve, a place for the test specimen tube to be placed and a pressure gage. Air is delivered to the system at a constant pressure, while the drop in pressure is measured. The pressure gage is calibrated to show the permeability readings directly.

Common Uses
Testing the permeability of sand molds used in the foundry industry.
