TLD001 Concrete Schmidt Hammer

Features Test strength of concrete material: slab, column, beam, truss. Used in civil engineering, construction etc Center rod is made from imported material, high accuracy and durable resistance. The shell is made form high quality Aluminum Alloy 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.
