HT-225B Concrete Test Hammer Portable Schmidt Type Rebound Hardness Tester for Strength Measurement

Consistent with GB/T9138-1988 standards and JJG817-93 statutes and JGJ /T23-2001 technical regulations.HT-225B Concrete Test Hammer generally applied to building components, bridges and all kinds of concrete   components (panels, beams, columns, bridges) strength.

1) Center guide rod using imported materials, high precision, wear-resistant;

2) Use of super-hard Engineering Plastics shell to avoid on-site work injury apparatus, to extend the service life;

3) 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.
