All Admesy products measure using the CIE1931 XYZ standard. From this colour space other colour space coordinates can be calculated. All Admesy instruments come with free software that can be used to perform all colour measurements.
Most commonly used for reflective measurement is the CIE L*a*b* colour space but other relative colour spaces are supported as well.

For E-reader measurements the Arges45 can measure colour and reflection (grey scales)
The Vates can be used to measure gloss, colour and reflection.
