The hardness of paper rolls is an important factor in the quality assurance processes of paper, film and foil industries.
If rolls are too hard, too soft, unevenly wound or have variable moisture levels this can cause difficulties when printing.
The Parotester 2 Roll Hardness Tester enables fast and accurate evaluation of the roll’s hardness, the hardness profile and the variation in hardness of paper, foil and film rolls.
Automatic loading and unloading of the impact body results in fast and repeatable tests with more resolution than the commonly used original Schmidt hammer test.
The Parotester 2 Impact Devices are also designed for long service life.
User-friendly electronics with a large LCD display of the measuring data with statistical values adds to the benefits of the Parotester 2 Roll Hardness Tester.
Data can be printed out immediately on the optional RS-232 printer. Information (about 5,000 single measurements) can be stored internally with individual roll identification and can be sent to a PC or printed via the RS-232 connection.
