0.735J Schmidt Test Hammer

    Schmidt hammer is specially used to test the compressive strength of light material
object such as brick,it also can be used to test all light bone material concrete and other
 light weight materials.Testing and determining compressive strength by test hammers
has many advantages, high efficiency, high accurate, and easy to operate,easy to carry,
easy to maintain, and the non-destructive testing.

Work principles of test hammer:
 

    Inside of test hammer, the rebound hammer can get impact energy by stretched spring,
and rebound hammer will impact the rebound pole, through rebound pole the energy will
be transmitted to test sample, then rebound hammer and rebound pole will be rebounded,
and the slider on the test hammer will move along with the rebound hammer till a highest 
point, and we can read the data by a scale, called rebound value.
