Overview
Emissions and Stack AC-115S Portable Paper & Textile Colorimeter is a compact, user-friendly tristimulus instrument tailored for measuring color differences between samples and standards. Designed for non-fluorescent substrates like textiles, paper, leather, and pigments, it delivers readings in L*a*b, ΔE*ab/C*ab/H*ab, Yxy, XYZ, RGB, whiteness/yellowness, and more. It includes statistical functions (max, min, average, SD), pass/warn/fail evaluations, and stores up to 99 datasets. Features calibration capability, auto power-off, USB and RS-232 output, and ships with standard accessories. Backed by a one-year warranty and global support.
