Proceq Silver Schmidt OS8200 Live

Concrete strength and uniformity evaluation
using optical rebound hammer technology

As accurate, reliable and versatile as ever. Now Live.

The global benchmark for non-destructive compressive strength estimation.

The optical measurement technology of Silver Schmidt Live delivers compressive strength measurements with a higher range and far lower dispersion than any classical rebound hammer. Its 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.
