KES - FB1 - A Tensile and Shear Tester

Function of the Tester This tester can analyze and mechanize the hand movements of craftsmen and professionals during the evaluation of fabric style and hand - feel, such as "stretching" and "cutting". It converts the results into objective numerical data, and can obtain data on tensile/shear stiffness, tensile energy, elongation, and resilience of fabrics, papers, non - woven fabrics, films, etc. Tensile and shear characteristic data affect the "elasticity" and "tension" of the style and hand - feel, which in turn affect "shape stability" and "tendency to produce patterns". Features - **Improve data accuracy**: The sample is de - relaxed between the motor fixture and the clamping fixture to avoid measurement errors. - **Display resolution**: 0.01, which can digitally represent the differences in minor tensile and shear characteristics. Examples of Measured Samples All fibers, fabrics, medical fabrics, automotive seat cushions, interior fabrics, non - woven fabrics, film samples Specifications - **Dimensions/Weight**: Electronic amplifier device, W230×D450×H500(mm)/20kg - **Power Supply**: AC100V, maximum power consumption 40W - **Measurement Environment Temperature and Humidity**: 20～30°C/50～70%RH, no condensation.
