Concrete Test Hammer is applied to test the compressive strength of building concrete components,bridge and so on.1）Center rod is made from imported material, high accuracy and durable resistance2）The shell is made form high Aluminum or high polymer material in order to perfect protect instrument from damage and extend use life.3) 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 Technical informationStandard impact energy2.207±0.1J (0.225Kgf.m)Radius of spherical tip25mm±1mmThe static friction of pointer slider0.65N±0.15NWorking Temperature-10℃~ 50℃Length of spring stretch75±0.3mmWorking Humidity≤90%RHAverage rebound hammer on steel anvil Rm80±2DimensionsΦ54x280mmMeasuring Range10~60MpaNet weightAbout 1.0Kg
