The Paper Tearing Strength Tester GT-N01B is a high-precision microcomputer-controlled paper tearing strength tester. It measures tearing resistance for paper, cardboard, leather, films, and composites, with pneumatic clamping and automatic release to ensure accuracy. Features include multi-directional testing (MD/CD/undefined), data storage for 100 results, and compliance with ISO, ASTM, TAPPI, and GB standards. Ideal for quality control in packaging, manufacturing, and R&D.
The GT-N20 Roughness and Air Permeability Tester is a high-precision laboratory analyzer designed to measure surface roughness and air permeability across a diverse range of technical substrates. Engineered to perform the standardized Bendtsen method, this equipment natively calculates Gurley Porosity equivalents directly from measured flow values. It guarantees full compliance with global standards including ISO 8791, ISO 5636 and DIN 53120.
