The SpectraProbe® XE on-line spectrophotometer provides continuous, on-line color measurement of your paper product. The system provides real-time data display so that adjustments can be made during the process, without having to make a tear at the roll and waiting for lab results. Using 0°/45° optical geometry, the SpectraProbe XE correlates to laboratory measurements. The UV control option allows optically brightened paper to be accurately measured.
