Langry RH450-A High-Strength Concrete Test Hammer
High impact energy (4.500 J) test hammer engineered specifically for testing high-strength concrete elements (60 to 100 MPa) in tall buildings and mega bridges.
Key Engineering Highlights
- ✓ Elevated nominal impact energy of 4.500 Joules for high-strength concrete
- ✓ Linear measuring range from 60 to 100 MPa compressive strength
- ✓ Heavy-duty hardened alloy construction resistant to jobsite wear
- ✓ Special impact spring with 900 ± 40 N/m stiffness
- ✓ Calibrated against certified high-energy steel test anvils (88 ± 2)
Technical Overview & Compliance
The Langry RH450-A High-Strength Concrete Test Hammer is designed to overcome saturation issues encountered when standard 2.207 J hammers test concrete above 60 MPa. With a rated impact energy of 4.5 Joules, it accurately measures compressive strengths up to 100 MPa in high-rise building pillars, pre-stressed highway girders, and heavy infrastructure projects.
