Digital Bursting Strenght Tester (D1model)

The Bursting Strength Tester is designed to find bursting strength of fabric/leather/paper/paper board. A test specimen is held between two annular clamps under sufficient pressure to minimize slippage. The upper clamping surface which is in contact with the test specimens has a continuous spiral grooves. The upper clamping surface move up and down by an electro-pneumatic system. The clamping force may be adjusted by adjusting the pressure of pneumatic system with the help of pressure gauge and pressure regulator. A circular diaphragm of pure gum rubber is clamped between the lower clamping plate & pressure cylinder so that before the diaphragm is stretched by pressure underneath it the center of its upper surface is below the plane of the clamping surface.
