Concrete test hammer RH225-A

rebound

Langry RH225-A concrete test hammer used for testing the compressive strength of ordinary concrete in the range of 10 to 70 N/mm² (1'450 to 10'152 psi) in structural engineering. Main Feature High quality raw materials Imported high-quality springs are more fatigue-resistant, aluminum alloy spring seat snap ring assembly. Improved pointer design, easy to adjust friction and more stable. Abrasion resistance of super hard 6061 aluminum alloy casing, and the button is not easy to fall off by stretching process. Precision machining technology Adopt CNC machining center and other machine tools to refine the movement, and the rebound value is guaranteed. Finely grind the spherical zero-setting screws to make therebound firing smoother and smoother. High-precision aluminum alloy flange is not easy to be damaged, and high-precision hook is not easy to be elastically emptydue to abrasion. User friendly design Silicone bracket for soft hand protection, more comfortable rebound operation. Beautiful label and ruler are easy to read, and the hard oxidation treatment of the parts is beautiful and durable. Multiple original imported dust-proof components, cleaner movement and longer maintenance period.
