Application field Used for testing the compressive strength of ordinary concrete in the range of 10 ~ 60Mpa in structural engineering.

Product features and advantages

(1) Imported high-quality springs are more fatigue-resistant, aluminium alloy spring seat snap ring assembly
(2) Adopt CNC machining center and other machine tools to refine the movement, and the rebound value is
guaranteed.
(3) Silicone bracket for soft hand protection, more comfortable rebound operation.
(4) Finely grind the spherical zero-setting screws to make the rebound firing smoother and smoother.
(5) Improved pointer design, easy to adjust friction and more stable.
(6) Beautiful label and ruler are easy to read, and the hard oxidation treatment of the parts is beautiful and durable.
(7) High-precision aluminium alloy flange is not easy to be damaged, and high-precision hook is not easy to be
elastically empty due to abrasion.
(8) Multiple original imported dust-proof components, cleaner movement and longer maintenance period
(9) Abrasion resistance of super-hard 6061 aluminium alloy casing, and the button is not easy to fall off by stretching process.
