Concrete rebound test hammer is suitable for testing the compressive strength of general building components, bridges and such
components (plate, beam, column and bridge).
Characteristic:
1) The center guide rod is made of material with high precision;
2) The shell is made of duralumin;
3) The pointer slider adopts external spring coil structure, which is not only convenient for friction adjustment, but also can
ensure uniform friction between pointer shaft and pointer slider.
