Paper bursting strength tester is for the bursting strength of paper, which is designed in accordance with ISO2758 Paper-Determination of bursting strength' Paper bursting strength tester Principle A test piece is placed over a circular elastic diaphragm which is rigidly clamped at the periphery but free to bulge with the diaphragm. Hydraulic fluid is pumped at a constant rate, and bulged the diaphram until the test piece rutures. The bursting strength of the test piece is the maxium value of the applied hydraulic pressure. Materials: paper, foils, corrugated, textiles Paper bursting strength tester Technical features 1 LCD display and PVC operation panel 2 Automatic test process, automatic bursting judgment 3 Microcomputer real time data collection and data memory 4 Micro printing 5 Synchronous motor drive for stable and precise pressure output Paper bursting strength tester parameter (For paper) Measuring Range: 20~1600kpa Accuracy: + / - 0.5% or less(≤±0.5%) Resolution: 0.01 kpa Deformation Error: 1 mm or less Plates Concentricity: 0.25 mm or less(≤0.25mm) Diaphragm resistance : bulge height (9±0.2)mm/(30±5)kPa Transmit hydraulic volume: 95±5ml/min Pressure Plate Diameter: upper:30.5±0.1mm, lower: 33.1±0.1mm Display: 3.5 in. 320*240 Lattice LCD with curve display Clamping Force: 400kpa~1200kpa (adjustable)
