It is an ideal equipment widely used in packaging, paper making, quality inspection and many more. Digital Edge crush tester is a useful instrument for determining the compression strength of solid fibre boxes and corrugated boxes by testing the paper or board used in making such boxes.
It is an important procedure followed to find out the stiffness of CFB on edgewise. Higher the edge crush value of the test specimen higher will be the strength of side of the box.
Presto’s Edge Crush Tester is a rigid compression tester designed specially to perform ASTM and TAPPI material tests on corrugated board.
The lab testing instrument can be easily used as ring crush tester and flat crush tester too as per the standards. The lab equipment is designed in table top style with user -friendly features.
The ECT value depends on the paste bonding. The higher edge crush value represents the stiffness of the Corrugated box. Hence, the instrument is used to compare the quality of the corrugated box. It is also possible to determine the compression strength of the box by using ECT value in the McKee’s formula.
