KES-SESRU surface roughness/friction tester

Produktintroduktion:

This tester analyses and mechanizes the "stroking" hand movements taken by craftsmen and professionals when evaluating the style and feel of fabrics, and can replace the results with objective numerical data, which can obtain the data of friction coefficient, friction coefficient change, surface roughness. Based on these readiness values, objective data can be used to evaluate and quantify the "smoothness", "smoothness" and "roughness" of touch with the hand. Also suitable for soft touch conditions or hair measurement.

Egenskaper:

Quickly test the sense of friction, simulating the frequency band signal felt by hand contact

Correctly analyze and express how the task feels when touching objects

The smoothness of contact is calculated by changes in the coefficient of friction

The relationship between the feeling of friction （smoothness） felt by the touch of the human finger

MIU correlates with how easily a person's fingers slide when touching a surface.

The higher the value of MIU, the less smooth it is.

MMD correlates with how smooth or rough a person feels when they touch a surface with their fingers.

The larger the value of MMD, the rougher the surface of the object.
