Pneumatic Bursting Strength Tester

The METLOR INDIA Pneumatic Bursting Strength 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 type instruments are also available. Digital type pressure gauge with pneumatic clamping model also available.
