By measuring RHO at many places across the face of a wound roll, a PROFILE of the roll hardness can be obtained. The Profile shows the uniformity of roll hardness across the width of the roll. Ideally, a roll should show the same RHO value across it's entire width. As data is collected by the Bel-2000, It shows a graph of the roll profile.
