Introduction

The CM-3630 bench-top spectrophotometer ensures perfect compliance to optical standards ISO 2469 and ISO 2470 used in the Pulp and Paper Industry. Together with the designated 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 makes calibration and adjustments to whiteness and tint a fast and easy procedure. In fact, in just a few seconds your instrument is perfectly calibrated, much faster and with conventional instruments. Since everything’s done numerically, and with the significant reduction in moving parts, it is almost maintenance free
