CM-3630 Benchtop Spectrophotometer

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 color, 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.

Features

  • ◉ Bench top model with d/0 geometry
  • ◉ Provides exact conformity with ISO standards 2469 and 2470 for Pulp & Paper industry.
  • ◉ Especially designed for paper, pulp and cellulose industry and complies all the European & American international standards such as SCAN, DIN, TAPPI, CPPA and AFNOR.
  • ◉ Patented Numerical UV control (US patent No. 5,6,36,015) specifically required to find out brightness of paper as per ISO 2469 & 2470. Simultaneous Calibration of Whiteness & ISO Brightness.
  • ◉ Exclusive FMS Paper Control Software provides Fluorescence, Residual Ink Calculation (ERIC], Scattering and absorbtion coefficient and other measurements like Brightness (ISO 2470), L*a*b*, L*C*h,Whiteness Index /Tint (CIE/Ganz/Griesser) Yellowness Index(ASTM E313/ASTM D1925).
  • ◉ Opacity Jig enables quick measurement of opacity by turning inbuilt Black and White standard surface.

Application
