Concrete rebound hammer Original Schmidt OS8000 application

Concrete rebound hammer — Original Schmidt OS8000

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

Versatility, digitally enhanced

Original Schmidt OS8000 works as a:

  • digital hammer with digital reporting and data sharing (via the free, comprehensive Apple iOS app or Android app)
  • digital print console by wirelessly connecting to a Bluetooth printer and directly printing out test results
  • stand-alone digital hammer (using the digital display without the app and downloading the data to the app later, if required)
  • stand-alone analog hammer (using it like an Original Schmidt hammer with the mechanical display, even without a battery)

Test on-site and share results up to 80% quicker compared to analog hammers. Eliminate operator errors thanks to automatic impact angle correction and series evaluation according to standards, as well as wrong or misplaced data thanks to cloud synchronization of your measurements.


User-friendly mobile apps

  • Allows you to test in accordance with major standards
  • Visual reports are generated using lists, bar charts, and statistics
  • Records data from the app to a web reporting tool
  • Report export options of PDF or CSV
  • Records GPS locations, enables adding notes, images and audio comments using the Logbook feature for full
  • measurement activity traceability. Logbook feature for full measurement activity summaries
  • Hammer verification management to help keep hammers calibrated as required by standards
  • Impact results can be heard live in audio on Apple iOS devices via text-to-speech
