Precision Hydraulic Mullen Burst Testing Engineered for Heavy-Duty Packaging & Cardboard Quality Control.
The ITM-LAB RS-8403A is an industrial-grade, microcomputer-controlled Bursting Strength Tester designed to measure the maximum resistance of materials subjected to increasing hydraulic pressure.
Widely recognized as a definitive Mullen-style tester, this machine is essential for manufacturing lines, QA laboratories, and packaging facilities testing corrugated cardboard, multi-layer paperboard, robust textiles, synthetic leather, and heavy packaging foils.
Armed with a broad testing spectrum spanning 0 to 100 kg/cm2, a high-rigidity clamping mechanism, and an ultra-precise oil pressure transducer system, the RS-8403A captures exact material rupture points.
The system comes pre-loaded with global formula algorithms to ensure seamless compliance with international test methods including ISO 2759, ASTM D2210, TAPPI T403, and JIS P8112.
Structural Engineering & Performance Advantages
Replaces unreliable analog gauges with a high-speed digital sensor capturing rapid hydraulic peaks at the exact millisecond of specimen rupture.
Utilizes an optimized 85% synthetic ester and 15% distilled water compound to guarantee smooth, non-compressible pressure propagation under varying ambient temperatures.
Driven by an industrial 1/4HP shock-proof electric motor, providing consistent hydraulic flow velocity and zero-drift mechanical clamping forces.
Displays real-time peak force, automatically calculates average bursting resistance across test batches, and enables quick data resets for fast-paced industrial workflows.
