Brick Rebound Test Hammer - Mechanic Type, Schmidt, Type L
- Product Code: CN501
Application:
CN381 test hammer born with smaller impact energy
is specially used to test the compressive strength of light material objects
such as brick. And also can be used to test all light bone material concrete
and other lightweight materials.
Testing and determining compressive strength by
test hammers has many advantages, high efficiency, high accuracy, ease of
operation, easy to carry, ease of maintenance, and non-destructive testing.
Work
principles of test hammer:
Inside of test hammer, the rebound hammer can get impact energy by stretched spring, and the rebound hammer will impact the rebound pole, through the rebound pole the energy will be transmitted to the test sample, then the rebound hammer and rebound pole will be rebounded, and the slider on the test hammer will move along with the rebound hammer till the highest point, and we can read the data by a scale, called rebound value.
