Hydraulic Bursting Strength Tester for Corrugated Board 2000 kPa

Hydraulic Mullen type burst tester with rubber diaphragm for measuring the bursting strength of corrugated board up to 2000 kPa. Used by corrugated sheet and box manufacturers for grade verification.

Specification

Hydraulic pressure expands a rubber diaphragm until the clamped board specimen bursts, and the maximum pressure is recorded. It is the traditional measure of corrugated board strength used to specify box grades. A digital model reads in kPa and kgf/cm2.

Features

• Range 0 to 2000 kPa with digital pressure sensor
• Hydraulic motor-driven pump
• Pneumatic clamp with 31.5 mm aperture
• Auto reset after rupture
• Includes calibration check diaphragm
