Original Schmidt OS800 - Concrete rebound hammer

Less coring, with concrete strength and uniformity evaluation using 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, and make it possible to drastically reduce the need for concrete coring.

Original Schmidt OS8000 is the Original concrete test hammer, now digitally redefined — and it is also the most advanced R-value hammer ever made, with unmatched performance, ease of use, and versatility. Paired with our user-friendly mobile apps, Original Schmidt OS8000 increases operator productivity and makes instantaneous reporting possible, from anywhere, any time.
