KES-FB4-AUTO-A
Automatic Surface Tester
カタログ

This automated tester is designed for measuring the surface property for fabrics, paper, nonwovens, and film-like materials.
Frictional properties, and geometrical surface roughness can be measured by this tester.
After mounting a specimen, press the start switch Surface and roughness sensors are automatically set in position to start measurement.
After one measurement is completed, the sensor moves to measure a different position of specimen. In total, three different positions of specimen can be measured automatically.
MlU = Mean coefficient of friction(μ)
MMD = Mean deviation of MlU

Highest detectable sensitivity in surface contour is 0.5μ.
In surface property, a low-cut filter is set in the circuit to exclude the component over 1mm wave length so that data should correlate with finger-feeling.
