4.5 joule impact energy, developed for the high strength concrete a standard 2.207 joule hammer cannot read.
Model RH450-A
Langry RH450-A Concrete Test Hammer
High strength concrete is now routine on high rise work, and a standard rebound hammer runs out of scale on it. The RH450-A raises the impact energy to 4.5 joules to bring C50 to C100 grades back into range, with a high toughness alloy spring and a CNC machined movement behind it.
