The measurement is based on measuring the deceleration of an impact hammer hitting the sample over 30 times per second while simultaneously measuring the location of the profiler.

 The device has a barcode scanner which can be used to automatically create or activate a roll folder. During measurement, the current hardness, location and speed are shown on the display.

Tapio RQP Live is a handheld roll hardness profiler for fast, objective quality control on the production floor. It measures a continuous hardness profile across the roll width, displays the results immediately, and transfers the data to the included Tapio RollView software for further analysis and reporting.
