Brief introduction:
The test hammer submits to standard of GB/T9138-1988 andJJG817-93 and JGJ/T23-2001. SY-225 concrete test hammer is appliedto test the compressive strength of building concrete components,bridge and so on.
Trait:
1) Center rod is made from imported material, highaccuracy and durable resistance.
2) The shell is made form high Aluminum or high polymermaterial in order to perfect protect instrument from damage andextend use life.
3) Pointer slider is outside structure, its friction canbe balance well and easy to be adjusted so that we can make surethat the instrument is accurate. Compared with other suppliers inthe line of business, the product is more accuracy, good quality,best price and longer use life.
