ⅱ Display directly thousands of color’ s chromatism
ⅲ Display color result by Lab、△E and Lch
ⅳ Three standard optical light sources: D65、D50and F11
ⅴ Samples and groups of color difference can be saved
ⅵ do the metamerism analysis itself or by PC software
ⅶ 4pcs AAA(1.5v)batteries, low power consumption
ⅷ Small volume、light weight and convenient operation
4. Technical Specification
5. Working Theory
Compare the color difference between sample and the measured subject, then
output the data of CIE_Lab , and △E,△L,△a,△b.
△E represents the total color difference.
△L+ represents partial white, △L- represents partial black
(comparing with prototype)
