Application field
It is used to test the compressive strength of ordinary concrete in the range of 10-60Mpa in structural engineering

1. Product features and advantages

(1) Imported high-quality springs are more fatigue-resistant, aluminum alloy spring seat snap ring components
(2) Using CNC machining centers and other machine tools for finishing movement, the springback value is guaranteed.
(3) Silicone bracket, soft hand guard, more comfortable rebound operation.
(4) Finely grind the spherical zero-setting screw to make the rebound firing smoother.
(5) Improved pointer design, easy to adjust friction and more stable.
(6) The beautiful scale is clear and easy to read, and the parts are hard oxidized, beautiful and durable.
(7) The high-precision aluminum alloy flange is not easy to be damaged, and the high-precision hook is not easy to be empty due to wear and tear.
(8) Multiple imported dust-proof components, the movement is cleaner and the maintenance cycle is longer
(9) The super-hard 6061 aluminum alloy shell is wear-resistant, and the key stretching process is not easy to fall off.
