Simultaneous measurement of SCI (specular) and SCE (specular component excluded).
In just 1.5 seconds, while the measure SCI and SCE data obtained will be displayed on the LCD. Spectrophotometer with traditional difference is, no between SCI and SCE mode switch maneuver. Since the measuring area does not change when switching mode, thus improving the work efficiency and provide a stable measurement data. And gloss digital display monitor can show the relative gloss.
It can be used in plastics, paints, resins and consumables
* SCI is a method to measure the specular reflection is included. For this reason, it is the surface of the sample to reduce the impact to a minimum, especially for color quality monitoring and computer color matching.
* SCE is a measurement method to exclude specular reflection. This type of measurement results obtained by visual observation of relatively similar.

△ b + represents yellow, △ b- represents bluish
Color range (tolerance)
0 - 0.25 △ E is very small or no; ideal match
0.25 - 0.5 △ E minor; acceptable match
