Concrete Test Hammer - Mechanic Type, Schmidt, Type N, Portable Mechanical Concrete Rebound Hammer Tester, Concrete Compressive Strength Tester, NDT Resiliometer Schmidt Hammer

Standard: EN 12504-2, BS 1881:202, ASTM C805

Application:

CN500 Concrete rebound hammer is a classic measuring method .non-destructive test of the compressive strength of concrete construction.

A concrete test hammer is applied to test the compressive strength of building concrete components, bridges, and so on

Advantage:

The center rod is made from a high-accuracy and durable resistance materials
The shell is made from high Aluminum or high polymer material in order to perfectly protect the instrument from damage and extend its useful life.
The pointer slider is an outside structure, its friction can be balanced well and easy to be adjusted so that we can make sure that the instrument is accurate.
