The Digital Bursting Strength Tester is engineered to accurately determine the bursting strength of paper and paperboard materials. It measures the pressure required to rupture a sample when subjected to increasing hydraulic pressure applied via a rubber diaphragm.
Widely used in packaging, printing, and paper manufacturing industries, this tester ensures consistent quality and performance evaluation of paper products like cartons, corrugated boxes, and boards.
✨ Key Features
- Digital display for accurate and clear reading of burst pressure
- Automatic hydraulic pressure build-up and release
- High-precision pressure transducer ensures test repeatability
- Robust clamping mechanism prevents sample slippage

❓ Frequently Asked Questions (FAQs)
Q1: What is the purpose of a bursting strength test?
It determines the pressure at which paper or board ruptures — an indicator of its strength and durability.
Q2: Can this tester be used for corrugated board?
Yes, it is suitable for single- and multi-ply board materials.
Q3: Is the instrument calibrated before delivery?
Yes, every unit comes with a factory calibration certificate traceable to ISO standards.
Q4: How often should calibration be performed?
Periodic calibration (typically once a year) is recommended to maintain accuracy.
