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.

Using the Parotester 2, 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 such roll 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 results in fast and repeatable tests of greater resolution than the commonly used Original Schmidt type L hammer test.

Features
•The Leeb hardness value (HL) immediately indicates the winding tightness. The measurement is objective and precise and leaves no space for vague interpretations
•The high resolution (1 LU) facilitates comparatively small differences in hardness to be revealed
•The large LCD display enables an immediate visual assessment of the values
•The unit can be easily programmed for individual user requirements
•About 5’000 single measurements can be stored internally. The data can be retrieved via RS 232C for further processing on a PC (use Parolink 3 or Hyperterminal software) or directly printed
•Using the external barcode reader (accessory part), roll identifications can be quickly captured and accurately read from the barcode of rolls
•The Parotester 2 is robust, requires little maintenance and is designed for long service life
