Concrete Test Hammer, Schmidt Hammer (ZC3-A)

ZC3-A Concrete Test Hammer,schmidt hammer
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. Our concrete resiliometer has been approved as "Recommended Product for Engineering Construction" by the Ministry of Construction. Shanxi Institute of Building Research, who composed "Testing Concrete Compressive Strength Technical Regulation of JGJ/T23-2001 with Springback Method", supervises the manufacturing process.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: Length of pointer20.0±0.2mmFriction of pointer0.65±0.15NSphere semidiameter at the end of the flip rod25±1.0mmRigidity of flip tensioned spring785.0±40.0N/mLocation of flip hammer's hook release"100" at the scale markWork length of flip tensioned spring61.5.0±0.3mmStrike length of flip hammer75±0.3Hop location of the flip hammer"0" at the graduated scaleFixed value of steel anvil80±2 (our products are controlled between 80-81)
