• Cobb Tester consists of a brass (or gun metal) cylinder of known inside diameter and length. It has a metallic plate, which is used for clamping the one side of the cylinder with the help of bracket and bolts. 
• The metallic plate, which is used for clamping purpose, is paste a rubber sheet for the perfect clamping. The whole assembly of the cylinder and clamping arrangement is pivoted so that easy and fast pour off the water takes place. A brass roller of specified size and shape is also provided with the instrument.
• The equipment is designed to give a long and trouble free life; the components are bright polished and bright chrome platted.

           Bursting strength tester of any material such as fabric, leather, paper, paper board & corrugated box etc. Its strength under multi- directional force and is defined, as the hydrostatic pressure required producing rapture of the material when pressure is applied at a controlled increasing rate through a rubber diaphragm.

               The ASIAN Bursting Strength Tester is designed to find bursting strength of fabric/ leather/ paper/paper board & corrugated box. A test specimen is held between two annular clamps under sufficient pressure to minimize slippage. The clamping is done by hand wheel/screw arrangement or by pneumatic pressure with pressure gauge, solenoid valve and pressure regulator as per model. The upper clamping surface which is in contact with the test specimens has a 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 plane of the clamping surface.

                The equipment is fitted with a motor driven screw 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 (or pressure sensor and digital indicator with peak hold and tare facility in digital model) gives the bursting pressure.

                The equipment is raggedly 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.
