Silver Schmidt OS8200 - Optical rebound hammer

Concrete strength and uniformity evaluation using patented optical rebound hammer technology.

Silver Schmidt OS8200 is as accurate, reliable, and versatile as ever — and now, connected, thanks to its optical measurement technology paired with digital productivity featues and user-friendly mobile apps.

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