PhaseView's optical instruments can discriminate between low and high abrasive thermal coatings and measure bumps of rolls.

For measuring bumps on heavy rolls, the sensor head as vibration insensitive equipment can be easily brought in the production area.

Measuring coated paper is important in off- and on-line coating manufacturing control. The ability of non-contact measurement of both roughness and heights in a fraction of a second results in an important productivity gain and maintenance cost savings.
