Hammer Test HT225Q


Metode pengujian hammer test dapat diterapkan untuk menilai keseragaman beton di tempat, untuk menggambarkan variasi kualitas beton di seluruh struktur, dan untuk memperkirakan kekuatan yang telah di aplikasikan


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 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.
