A vertically aligned Spectrophotometer in compliance with ISO standards used in the pulp and paper industry including ISO 2469 and ISO 2470. The instrument features a numerical UV-Control system which simplifies the process of calibration and measurement of colour, whiteness, and yellowness.
Highly competitive markets, such as the paper, pulp and cellulose industry, require a commitment to top quality throughout. The CM-3630 benchtop spectrophotometer ensures compliance to optical standards ISO 2469 and ISO 2470 used in the Pulp and Paper Industry. Used in combination with PaperManager software, values for colour, brightness, whiteness, and yellowness indices are calculated and displayed in full accordance with several international and national standards such as ISO, SCAN, DIN, TAPPI, CPPA and AFNOR. Numerical UV-Control greatly simplifies calibration and adjustments to whiteness and tint. In just a few seconds, the CM-3630A is calibrated and ready for measurement, much faster and with conventional instruments. Utilising Numerical UV-Control results in a significant reduction in moving parts and reduced maintenance requirements.

Spectrophotometer dedicated for The Pulp & Paper Industry
The Opacity Jig CM-A134 is equipped on one side with a white tile and on the opposite side with a black cavity and allows quick and precise opacity measurements of paper, films and similar materials. The Opacity Jig can be simply attached and de-attached without tools, but thanks to the turn able sample holder the Opacity Jig can be used also for thin samples for reflectance measurements.
