Concrete Test Hammer

    WTC-H beton rebound instrument series

are used for no disrepair structure and .

beton compressive strength,it can deduce the

strength of beton component by detecting

surface rigidity of beton component, the

instrument adopt Fixed value attack of a

projectile springs drive attack of a

projectile hammer, the one end of attack of

a projectile touch the other end of the

attack of pole on beton component, it will 

bring rebound power, the attack of hammer

push the finger and get the pointer data.

    It is with reasonable structure, small

volume, light weight and easy for proofread

and schleping.
