A Schmidt Rebound Hammer is a device used to evaluate the Relative Strength of concrete and other materials. The most common form factor has a mechanism similar to a nail punch, the impact energy that is "bounced" back from striking the surface of the material is converted to a dimensionless Index, related to surface hardness.
Users may convert this index to MPa strength using a Conversion Curve, compare this index to areas with Destructive Test results, or create their own Conversion Curve
There are also specialist versions for Rock Strength, Super Low strength concrete or mortar and Paper Roll testing.
The following chart shows the relative strength range of each hammer in the Screening Eagle Technology / Proceq range.
