Use/Good point

This apparatus is used to measure the textile, paper and other products’ resistance when broken by an external force at the same time from multi-angles, namely it is called the bursting strength.
When specimen fixed at the chuck is pressed up and broken by rubber diaphragm giving oil pressure, its resistance value is digitally displayed. Obtain the bursting strength (MPa) by the formula below,
The maximum strength is displayed at peak hold, yet it displays the rubber diaphragm pressure when the peak hold is removed.
Bursting strength (MPa) = A-B
Where, A = strength of rubber diaphragm to burst specimen (MPa)
B = strength of rubber diaphragm when clamp is removed (MPa)
*The unit between(kPa)and(kgf/cm²)can be exchange with button on the display。
