ColorXRA 45 Pulp Measure Pulp Color and Brightness In paper production, color and OBA information is first available at the pulp stage. While the readings are not the same as on finished paper, a color shift in the pulp is an indication that there will be a color shift in the wet paper and final product. The ColorXRA 45 Pulp is a compact, 45:0 inline spectrophotometer to measure color, whiteness, and brightness in thick pulp. Identifies Color Shifts During the Pulp Stage for Early Corrections The ColorXRA 45 Pulp spectrophotometer is mounted in a stainless steel housing and measures inline, directly into the thick pulp (concentration of 3% to 5%) through a bypass system. This device can measure color, whiteness, and optical brightness to identify shifts before they impact the final product. With a broad spectral range from 330 nm to 730 nm with a 1 nm resolution, this device delivers excellent color data for both visible and UV spectrums. Reduces Raw Material and Dye Usage When blending two lines of raw material, such as dark and light, to a constant level, color and brightness can shift. The ColorXRA 45 Pulp monitors this during production to control the addition of waste and visualize the homogeneity of the pulp after each dye addition to ensure optimum dye consumption without significantly changing the color of the total pulp for increased product quality. Enables Objective Pass/Fail Decisions The ColorXRA 45 Pulp delivers excellent short-term stability due to its use of real dual beam measurement, and its automatic wavelength calibration ensures exceptional measurement accuracy and long-term stability. It is a must-have color measurement instrument to make objective color assessment for pulp manufacturing and is the ideal complement to ESWin QC software, the ColorXRA 45 Lab, and the ColorXRA 45 Inline for a complete measurement system for paper machines.
