Feature
●★ HT-225 Concrete Test Hammer generally applied to building components, bridges and all kinds of concrete components (panels, beams, columns, bridges) strength.
●★ Center rod is made from imported material, high accuracy and durable resistance.
●★ The shell is made form high Aluminum in order to perfect protect instrument from damage and extend use life.
●★ Pointer slider is outside structure, its friction can be balance well and easy to be adjusted so that we can make sure that the instrument is accurate.
●★ Compared with other suppliers in the line of business, the product is more accuracy, good quality, and best price and longer use life.
