Speed ​​accuracy: ± 1% Paper Tensile Strength Tester Product Use : The paper tensile strength tester is a tensile strength tester for determining the tensile strength, elongation at break and tensile energy absorption of paper and paperboard and other similar sheet materials. The test machine is a monofilament vertical structure, and the upper and lower clamps are connected by a universal joint to ensure the concentricity of the clamping. The sample is easy to hold and durable. The electronic measurement and control technology is applied, and the liquid crystal screen displays the force value, the elongation and the time for breaking the sample ; the software automatically adjusts the appropriate speed according to the requirement that the standard tensile speed is broken within 20 s ± 5 s . The micro-printer prints a test report with complete functions, simple structure, and convenient operation and maintenance. Fourth, paper softness tester (test softness) Paper Softness Tester Execution Standard : GB/T 8942 Paper Softness Tester Functional Use : The Paper Softness Tester is a test instrument that simulates the softness of the hand. It is suitable for the softness measurement of high-grade toilet paper, tobacco sheets, fabrics and other materials. The instrument measurement and control system adopts the digital circuit technology with single-chip computer as the core. It has the advantages of advanced technology, complete functions, simple and convenient operation, etc. It is an ideal testing instrument for papermaking, scientific research units and commodity inspection departments.
