How to Calibrate

The Electronic Universal Sand Strength Machine determines the strength properties of clay and/or chemically bonded foundry sand specimens. This strength machine applies pressure on a sand specimen until failure to calculate the maximum force needed to break the specimen and then digitally displays the test results. This advanced electronic technology is capable of running over ten different sand strength tests.

A fully automatic system which measures the permeability of porous sand masses, both in compacted and loose states. Simply place your specimen on the rubber pedestal and press start. With the addition of specifically designed accessories, the Permmeter can also measure the permeability of raw foundry sand, shell coated foundry sand, and refractory coatings that are used in the foundry industry.

This instrument was designed to mimic the compressing action of an automatic molding machine in order to measure the effects the sand has upon its compactionabilities. Also, the device prepares standard 2″ x 2″ AFS or 50mm x 50mm metric sand specimens. The standard sand specimen is used in various tests including permeability, compressive strength, shear strength, etc.
