Detailed Product Description
HT-225D / HT-75D / HT-20D Automatic Schmidt Hammer Test LED Display Data Software to PC
HT-225D is an integrated digital concrete test ham?mer 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.
