Proceq Roll Hardness Tester – Parotester 2

The Parotester 2 roll hardness tester provides accurate and reliable evaluations of the roll hardness, hardness profile and hardness variation of paper, foil and film rolls. With Proceq’s roll hardness tester, unevenly wound reels can be spotted prior to interruption of operations and cause of quality problems in printing and converting operations.
By taking Leeb readings across the roll, uneven, too soft or too hard winding can be detected and the roll can be rejected. This minimizes the risk of complications e.g. during the printing process on paper.
Automatic loading and unloading of the impact body by pressing the impact device to the roll as implemented in the Parotester 2 roll hardness tester results in fast and repeatable tests of greater resolution than the commonly used Original Schmidt type L hammer tester.
