Langry RH75-A brick schmidt rebound hammer used for testing the compressive strength of rock in the range of 10 to 100 N/mm² (145 to 14500 psi).
The spring driven hammer is used to drive the hammer and hit the surface of the brick in the sintered common brick masonry or sintered porous brick masonry through the hammer rod to produce the recovery force of the instantaneous elastic deformation, so that the hammer drives the pointer to bounce back and indicate the bounce back distance, using the bounce back value as one of the indicators related to the compressive strength of the brick in the sintered common brick masonry or sintered porous brick masonry, to presume the compressive strength and grade of the brick
High quality raw materials
Imported high-quality springs are more fatigue-resistant, aluminum alloy spring seat snap ring assembly.
High-precision aluminum alloy flange is not easy to be damaged, and high-precision hook is not easy to be elastically empty due to abrasion.
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 the rebound firing smoother and smoother.
User friendly design
Silicone bracket for soft hand protection, more comfortable rebound operation.
Improved pointer design, easy to adjust friction and more stable.
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 longermaintenance period
