Schmidt Hammer AL-150 R
AMITTARI INSTRUMENTS
REBOUND TESTER AL-150R
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
