COL 45

Digital color meter to measure color and color differences in six color spaces for no lighting, non-fluorescent materials.

Features:
  • Six color spaces for measurement and comparison : (L*,a*,b*), L*, C*ab, hab), (Y, x, y), (X, Y, Z), (Rs, Gs, Bs) or (WI, YI, Tw). 
  • Statistics of max, min, avg and standard deviation displayed. 
  • Color difference tolerance can be set for PASS/WARN/FAIL tests. 
  • 9 different color targets can be stored for comparison. 
  • User calibration function. 
  • Data storage and recall. 
  • Low battery indication and auto power off. 

Applications:

This instrument can be used to measure the color of no lighting and non-fluorescent samples such as textile, paper, leathers, painting materials, etc. It can also be used for calculating color differences between two color in any of the six color spaces. It is a useful tool for quality control and wide industrial applications.  


Measuring Principle:

Color meter works according to the tristimulus absorption and imitates human vision. It does this by means of 3 color sensors with almost identical spectral sensitivity in the areas of red, green and blue. The color values determined in this way are represented as X, Y and Z values on the display and automatically converted to other color spaces.
