Description:
☆ Consistent withGB/T9138-1988 standards and JJG817-93 statutes and JGJ/T23-2001 technical regulations. HT-225 Concrete Test Hammer generally applied to building components, bridges and all kinds of concrete components (panels, beams, columns, bridges) strength.
☆ Center guide rod using imported materials, high precision, wear-resistant;
Pointer slider with external spring ring structure, both convenient for the friction adjustment,and ensures that the pointer shaft and pointer slider friction uniform, to ensure the accuracy of the instrument.Peer-products is relatively high accuracy, quality and cheap, long service life.
