The HD-A513-B Burst Strength Tester is an advanced testing instrument designed for measuring the bursting resistance of various packaging materials including corrugated paperboard, cardboard, and other paper-based packaging products. This precision equipment plays a crucial role in quality control processes for packaging manufacturers and testing laboratories.
Featuring a high-precision pressure transducer and digital LCD display, the tester provides accurate measurements with ±0.5% accuracy. The automatic operation system ensures consistent test conditions while maintaining specimen clamping force above 690kPa for reliable results. The unit offers switchable measurement units including kPa, psi, and kg/cm² to accommodate different testing standards.

The machine's stainless steel construction (SUS304) ensures durability, while the 31.5±0.05mm diameter test openings provide standardized testing conditions. With a compression speed of 170±10ml/min for high-pressure testing, the equipment efficiently evaluates material performance under controlled conditions.
Key applications include quality testing for packaging used in electronics, hardware, food packaging, furniture, and other industries where packaging integrity is critical. The tester complies with multiple international standards including ASTM-D2210, TAPPI T403, ISO 2759-2001, and GB/T1539.

Advanced features include automatic maximum value retention with audible/visual alarm when specimens break, power failure protection for data security, and optional printer connectivity for generating test reports. The computer-controlled system allows for easy operation through a user-friendly interface while maintaining high testing precision.
