For determining the Bursting Strength of Paper. Pressure is produced by electric motor and gear. Specimen is clamped between two concentric annuli by lever arm. Uniform pressure is produced and the plunger reverses automatically after rupture and saves testing time and increases diaphragm life.
The bursting pressure, at the time of rupture is recorded on a sensitive pressure gauge and digital display of test results. The gsm of paper can be feed in the test data and can obtain the results of burst factor also.
