China Digital Concrete Test Hammer (Ht-225D Ht75D Ht20d for Testing Concrete Brick or Mortar

Digital Concrete test hammer HT-225D/HT20D/HT75D for testing concrete, brick and mortar
HT-225D concrete test hammer/HT-75 concrete test hammer/HT-20 concrete test hammer is an integrated digital concrete test hammer which combines data processor and concrete test hammer into one unit. It is widely used for non destructive concrete testing quality 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.
