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.

By using the Parotester 2, unevenly wound reels can be spotted prior to interruption of operations and  prior to causing 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 rolls 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 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 winding tightness. Measurement is objective and precise and leaves no space for vague interpretations
• Thanks to the high resolution (1 LU), comparatively small differences in hardness can be revealed
• The large LCD display facilitates an immediate visual assessment of 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

Applications
