Color Meter FMG-30
User manual
1. Description of the instrument
Color meter enables measurement of the color intensity diff erence between a sample under examination and
a specimen. Based on a selected color palette, the device’s feedback information shows two colors most
closely related to the sample under examination and CIELab color space values L*a*b or the percentage
of the components of the sRGB color space. The instrument’s vertical construction enables measurement
of very small areas.

2. Measurement method
The color sensor and two electroluminescent diodes create a system based on a 45°/0° geometry. The sam-
ple’s surface is illuminated at 45 degrees. The sensor is placed at 0 degrees parallel to the sample’s surface.
The sample’s color is mapped out with dE2000, a color-diff erence formula based on the CIELab color spa-
ce, which describes the numerical diff erence between the sample’s surface color and reference.
