ZI 2068 concrete test hammer (Schmidt Hammer N type) is used to measure the compressive strength characteristics of hardened concrete non-destructively, control uniform concrete quality and detect weak spots in the concrete. The test object should have a minimum thickness of 100 mm.
The HT 225A Concrete Test Hammer is designed specifically for the non-destructive testing of concrete structures. This testing method has considerable advantages over conventional methods of assessing the compressive strength of concrete, in that large areas can be tested in a .

The Schmidt hammer is being widely used for estimating the uniaxial compressive strength (UCS) of rocks because of its simplicity, rapidity and portability. However, determination of the Schmidt hardness (R) in laboratory conditions is sometimes very difficult for weak rocks due to the fact that samples can be broken during the test, as well as sample scarcity.

The concrete test hammer or sclerometer is used for the non-destructive compression strength measurement of concrete. In such a way, concrete is tested for its load-bearing capacity and strength. The measuring principle is such that the concrete test hammer hits the concrete. Depending on the concrete hardness, the body rebounds, more or less.
The rebound hardness test can also be carried out using Schmidt hammer . Although the rebound index test is also useful in qualitatively estimating the UCS of rocks, it has proven inefficient .
