The model is the only one that covers the most completed test range from 0 to 12800cN.
reproducibility of the experimental conditions.
Automatic compensation for friction and leveling errors, no slave pointer, therefore no friction, alignment and maintenance problems.
Elmendorf tear tester (protear) enables rapid determination of the dynamic resistance of materials designed to be subject to strong shearing loads (e.g. fabrics) or liable to be damaged by sharp or heavy objects (e.g. paper bags). Subsequently, the test was naturally adopted for all materials in the form of sheet or films, cardboards, cloth, knitted fabrics, plastic films, aluminium foil, non-woven fabrics, complex flexible packaging etc.
Elmendorf type tear tester is not applied to sparse fabric or stretch materials which the tearing direction might be shift in test.
