TAPIO Technologies T A P I O® RQP – Roll Quality Profiler Tapio RQP: Measuring Principle The Measuring principle is to launch an impact body by spring force against the test surface on which it rebounds. Velocity and distance are measured and processed to form the hardness profile. RQP measures 10 times every second. Tapio Technologies Oy All rights reserved/ 2
