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.
