Concrete strength and uniformity evaluation using patented optical rebound hammer technology

Schmidt hammers by Proceq, the inventor of rebound hammer technology, have long been the global benchmark for non-destructive compressive strength estimation. Silver Schmidt OS8200 is as accurate, reliable, and versatile as ever — and now, connected, thanks to its optical measurement technology paired with digital productivity features and user-friendly mobile apps.

Our patented optical technology delivers compressive strength measurements with a higher range and far lower dispersion than any classical rebound hammer; and our versatile connectivity increases operator productivity and makes instantaneous reporting possible, from anywhere, anytime.

Digital versatility

Silver Schmidt OS8200 live works as:

• Connected digital hammer with instantaneous reporting and data sharing thanks to a user-friendly mobile app (Apple® iOS or Android™)
• Stand-alone digital hammer with automatic calculation of the rebound value.
• Digital hammer wirelessly connected to a Bluetooth printer for direct print-out of test results

Silver Schmidt accuracy

The Q-value brings greater accuracy at higher strengths.

Independent testing by the German Committee for Structural Concrete and the Bundesanstalt für Materialforschung und Prüfung (BAM) has consistently demonstrated that the Q-value featured in Silver Schmidt OS8200 is much better suited for working with high strength concrete. Furthermore, similar studies carried out in Germany, China and Japan have proven that the Q-value delivers tighter, more accurate correlations for custom material curves.
