★ Static friction between pointer slider and shaft:0.4-0.6N.

★ Average rebound values of calibration on steel anvil should be:74士2.

★ ZC4 test hammer born with smaller impact energy, is specially used to test the compressive strength of light material object such as brick. And also can be used to test all light bone material concrete and other lightweight materials.

Description:
ZC4 test hammer born with smaller impact energy, is specially used to test the compressive strength of light material object 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 accurate, and easy to operate, easy to carry, easy to maintain, and the non-destructive testing.

Principle
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.
