Roll Quality Profiler is designed for fast and accurate measurement of paper roll and machine roll hardness profile. Hand-held measurement device includes hardness measuring unit and distance encorder. Paper reels with non-uniform hardness profile may cause problems when printed or converted. RQP is the fastest and the most accurate system to detect reels that need to be excluded in printing or converting processes.
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.
