LNHHG Silver Rebound Hammer for Mortar Sclerometer Zc3 Concrete Test Hammer Sliver Schmidt Hardness Tester

LNHHG

1. **Precision-Engineered for Accurate Hardness Testing** This silver rebound hammer, also known as the Zc3 concrete test hammer and Schmidt hardness tester, is designed with strict adherence to HD-225A technical specifications. It delivers reliable and consistent readings for mortar, concrete, and similar building materials hardness assessments. 2. **Optimized Mechanical Parameters for Stable Performance** Equipped with a nominal energy of 2.207 J and spring stiffness calibrated to (185 ± 30 N/m), the tester ensures uniform impact force every time. The precisely controlled impact hammer stroke of (75.0 ± 0.3) mm further enhances the accuracy of rebound value measurements. 3. **Sensitive & Low-Friction Pointer System** The pointer system features a maximum friction range of 0.5 N ~ 0.8 N, enabling quick and clear response to impact rebounds without jamming or lag. Its standardized anvil rebound value of 80 ± 2 serves as a convenient reference for routine calibration checks. 4. **Wide Temperature Adaptability for Versatile Use** Built to perform in harsh working environments, this hardness tester operates smoothly within a temperature range of -10℃ ~ +40℃. It is suitable for both indoor laboratory testing and outdoor construction site inspections. 5. ** & User-Friendly Design for Long-Term Use** Crafted with sturdy materials, the silver rebound hammer resists wear and corrosion from dust, moisture, and accidental bumps on job sites. Its ergonomic structure ensures comfortable grip and easy operation, making it a practical tool for mechanics, construction workers, and material testing professionals.
