Portable, lightweight and easy to operate. It incorporates an LCD display that clearly indicates the hardness number and completely eliminates any operator error associated with reading a mechanical scale. The instrument automatically records the maximum penetration value.

Automatically ejects the specimen softly, ensuring high repeatability. Since the human “factor” can be eliminated, the test sample can be ejected without any further compaction.

This tester is designed to measure resistance to degeneration and plasticity of clay bonded sand upon impacting a target at a fixed velocity.

Designed to mimic the compressing action of an automatic molding machine in order to measure the effects the sand has upon its compaction abilities.

Used to prepare a standard AFS 2 in. x 2 in. (Metric 50 mm x 50 mm) cylindrical sand specimen for compression, shear, splitting, deformation and tensile tests.
