Schmidt Hammer AL-150 N & L Concrete Test Hammer AMITTARI INSTRUMENTS  REBOUND TESTER  AL-150 Digital rebound hammer concrete test  AL-150   Product Information : Rebound Tester also called Concrete Test Hammer,Elasticity Tester. 1. Normal impact energy: 2.207J 2. Use for concrete Non destructive test Description: The meter is in accordance with technical regulation of JGJ/T23-2001 , used for testing of concrete compressive strength within the scope  of 10-60Mpa, with the system standard energy of 2.207J, and value  indicating system of pointer direct reading. Characteristics: Light (saving 2/3 forces compared with counterpart products), flexible , inexpensive, power-free, easy to master; the button applies  stretching technics and is not easy to fall off; the pointer is easy to  adjust friction. Therefore, it is the first choice applicable for  on-the-spot NDT. Main Technical Parameter: 1. Length of pointer: 20.0±0.2(mm) 2 .Friction of pointer: 0.65±0.15(N) 3. Sphere semidiameter at the end of the flip rod: 25±1.0(mm) 4. Rigidity of flip tensioned spring: 785.0±40.0(N/m) 5. Location of flip hammer’s hook release: “100” at the scale mark 6. Work length of flip tensioned spring: 61.5.0±0.3(mm) 7. Strike length of flip hammer: 75±0.3 mm 8. Hop location of the flip hammer: “0” at the graduated scale 9. Fixed value of steel anvil: 80±2    Standards and Regulations Applied ISO/DIS 8045             International EN 12 504-2               Europe ENV 206                    Europe BS 1881, part 202      Great Britain DIN 1048, part 2        Germany                                                                                              ASTM C 805              USA NFP 18-417                France B 15-225                    Belgium JGJ/ T 23-2001          China  JJG 817-1993             China   Models N can be used for testing: - Concrete items 100 mm or more in thickness - Concrete with a maximum particle size ≤ 32mm Models L can be used for testing: - Items with small dimensions (e.g. thin- walled items with a thickness from 50 to 100mm)       Technical data:
