A versatile tool
Original Schmidt Live 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)
  • Original Schmidt Live: a comprehensive R-value rebound hammer for the concrete and paper industries and geologists.

Save time and obtain results with confidence

  • Test on site and share results up to 80 percent quicker with the Original Schmidt Live than with traditional test hammers. All raw data is stored instantly both on the device and on a safe and secure cloud.
  • Operator errors are eliminated. Impact angle corrections are made automatically. Series evaluation according to standards is fully automated.
  • Prevent read-out, transcription, and human errors, and avoid losing hand-written measurements, as all data is stored instantly on a safe and secure cloud.
