Roll hardness is a key parameter defining a good roll.

Identify problematic rolls easily using the mobile ACA RoQ Roll Hardness Profiler and avoid runnability issues.

Embedded touch screen, Wi-Fi and built-in barcode reader allow instant hardness profile displayed and versatile data handling possibilities as well.

The ACA RoQ analysis is not just a measure of roll quality, but also a great web quality tool.

Caliper variations are far too small to be picked up by online scanners or test labs. Hardness profile is an excellent indicator of paper or film material being level enough to be wound up.
