Pneumatic Bursting Strength Tester

  • This tester is designed to find bursting strength of fabric/ leather/ paper/paperboard & corrugated box. 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 continuous spiral grooves. 
  • 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 clamping surface. 
  • The equipment is fitted with a motor driven cam mechanism, which increases fluid displacement on the lower side of the diaphragm at a specified rate. 
  • The equipment is fitted with an arrangement, which automatically brings down the pressure and stops the motor on completion of the test cycle. A maximum reading type pressure gauge gives the bursting pressure. The equipment is ruggedly designed to give a long & trouble free life. 
  • The components are brighter chrome plated or painted in metallic paint to give the tester an aesthetic appearance. Digital type pressure gauge with pneumatic clamping model also available.
