Product Details

Rebound Hammer HT225D widely use Concrete Test Hammer, concrete hardness tester

Model:HT-225D

Product Description

HT-225D concrete hammer is an integrated digital concrete test hammer which combines data processor and test hammer into one unit.

It is widely used for non destructive testing quality of concrete and building materials in finished structure or prefabricated blocks. From its rebound value, the compressive strength of con¬crete can be calculated out automatically.

All testing data can be stored in memory and transferred to PC by USB cable or wireless by Blue tooth.
