Silver Schmidt Rebound Hammer

Silver Schmidt Rebound Hammer – Digital Concrete NDT Tester

The Silver Schmidt Rebound Hammer (OS-8200) is the most advanced analogue-digital rebound hammer by Proceq, combining the proven Schmidt impact mechanism with digital data capture and wireless reporting. It is the standard instrument for concrete compressive strength estimation in quality assurance on major infrastructure projects.

What Makes Silver Schmidt Different

• Q-Value measurement: Unlike standard rebound hammers that measure R-value (spring rebound), Silver Schmidt measures Q-value (coefficient of restitution) — a more accurate, physics-based measurement independent of impact direction
• Direction independence: No correction needed for upward, downward, or horizontal hammer orientation
• Digital display: Instant strength readout in MPa or N/mm² on integrated screen
• Data storage: Stores up to 3,000 impact values on device
• Wireless reporting: Bluetooth connection to Silver Schmidt App for PDF/CSV reports

Technical Specifications

• Impact energy: 2.207 Nm (Type N)
• Compressive strength range: 10–100 N/mm²
• Q-value measurement range: 0.1–1.0
• Display: Digital, backlit
• Battery: Rechargeable, 2,000+ tests per charge

Applications

• Highway and bridge concrete quality monitoring (NHAI, NHIDCL)
• Pre-qualification of concrete batches at RMC plants
• Structural health assessment and repair-or-demolish decisions
• NABL and third-party inspection reporting
