The coefficient of friction on a paper surface is one measure that indicates the surface condition of the paper. This COF tester measures the coefficients of friction in the following mechanism A 1-kg weight is placed on two overlapped sheets of the same specimen paper. While sliding the weight, coefficients of static and kinetic friction are read on a push-pull gauge. Optionally, a recorder can be installed to help read coefficients of static and kinetic friction more easily as well as to enable recording of changes of the kinetic friction force.
