Concrete Test Hammer Standard Concrete Testing Equipment
Standard:
EN 12504 PART 2 ASTM C805 DIN 1048 BS 1881:202 NF P18-417
Features:
- The imported high-quality Korean SWP piano spring has good anti
elasticity and anti fatigue performance;
- NBR seal dust ring, ensure the movement clean, extend the
maintenance cycle;
- CNC machining center and other machine tools refine the core to
ensure accurate and stable rebound value;
- Soft anti-wear hand rubber sleeve makes the rebound meter more
comfortable to operate;
- Fine grinding spherical zero adjusting screw, springback firing
more smooth;
- The improved pointer design is easy to adjust friction and more
stable;
- The high-precision aluminum alloy flange is not easy to be damaged,
and the high-strength hook is not easy to hang empty;
- The integrated design of the shell, the guide key and support are
permanently free from damage and falling off; the button adopts the
stretching process, which is not easy to fall off.
