is Kalstein using research and development of autonomous core technology of a portable light color difference instrument, is the high level spectral architecture color difference instrument, besides ensuring a precise relative ΔE at the same time, also to ensure the accuracy of the absolute value of L, A and B for a long time, anytime and anywhere can pass international standards and national measurement standards. Using built-in silicon photo diode matrix sensors (double row 24), import slate, Δ E*ab repetitive easily control within 0.1, both measuring speed and convenience of operation, without need to connect computer or software can quickly judge color difference Measurement, 8mm diameter meet plastic electronics, painting and ink, printing and dyeing textiles, printing...
