Lab Expo Mullen Burst Tester measures the pressure required to burst paper, with a 0–1600 kPa range and ±0.5% F.S. accuracy. These capabilities support measurement-based assessment of paper resistance for quality inspection.

The hydraulic system delivers pressure at 95 ± 5 ml/min, while microcomputer PID control regulates the testing cycle. Automatic maximum-value storage retains the peak burst pressure after specimen failure, making test results easier to retrieve for review.

Manufactured for packaging manufacturers, paper mills, and material testing laboratories, this bursting strength tester supports paper burst-resistance evaluation and routine quality control of paper-based materials.
