The force required for bursting or complete rupture of the board is measured through a Digital Indicator. The bursting strength defines the materials quality as compared to the others. Digital Bursting Strength Tester provides a hydraulic load under a rubber diaphragm of a specific area of the sample under test. It can be used to accurately determine the bursting strength of paper, corrugated cardboard, carton box, card board, leather, cloth or synthetic leathers. The bursting strength value is expressed in terms of kg/cm². Presto, one of the leading manufacturers of testing instruments offer wide range of paper and packaging instruments.
