Burst Strength Tester for Paper, Textiles and Leather – Automatic Digital Mullen-type
Introducing the upgraded version of our QualiBurst™ MP Automatic Mullen-type Digital Burst Strength Tester, designed to measure the bursting strength of paper, corrugated paper, cardboard, fabrics, leather, and more.
Upon sample detection, the QualiBurst™ MP Burst Strength Tester automatically grips it, conducts the burst test, and displays the results. The test piece, held between annular grips, is subjected to increasing pressure by a rubber diaphragm, which expands under hydraulic pressure at a controlled rate until the test piece ruptures. The maximum pressure reading up to the rupture point is recorded as the bursting strength.
WIDE APPLICABILITY:
Ideal for various industries, including paper, packaging, material science, leather, textile, automotive, and industrial manufacturing.
EFFICIENT TESTING SOLUTION:
Provides consistent pressure and ensures the sample and diaphragm inflate uniformly until the break point is reached.
BURSTING STRENGTH DATA:
Uses the maximum hydraulic pressure required to break the samples as an index to evaluate the strength and resistance of materials.
QUALITY ASSURANCE TOOL:
The QualiBurst™ MP plays a crucial role in quality assurance, ensuring the consistency and reliability of product quality by accurately measuring the strength of materials.
STANDARD CONFORMITY:
Ensures that products meet industry standards and satisfy quality expectations in the market.
