We are a leading manufacturer and supplier of paper testing equipment. Our factory-direct sale ensures top-quality instruments for accurate paper testing.
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.
The GT-N69B sealing tester designed for the quantitative and qualitative evaluation of packaging integrity. Utilizing the Vacuum Water Bath (Bubble Emission) method, this equipment is the industry standard for identifying even the smallest leaks in food, pharmaceutical, and medical packaging. Unlike manual alternatives, the GT-N69B automates the entire testing process—from vacuum pull to pressure maintenance and release—ensuring maximum repeatability and strict compliance with international standards such as ASTM D3078.
Brightness Tester is a specialized printing test machine for the brightness, transparency, fluorescence of toilet paper, paper, paperboard, adhesive sticker and surface of carton.
