China Digital Concrete Rebound Hammer Ht-225D Ht-75D Ht-20d with 4000 Data for Memory

HT-225D concrete test hammer/HT-75D concrete test hammer/HT-20D concrete test hammer is an integrated digital concrete 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 concrete 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.
