it is a compact and versatile instrument designed for precise color measurement across a spectral range of 400–700 nm. Featuring a 45°/0° optical geometry and switchable apertures (Ø 8 mm / Ø 4 mm), it is ideal for accurately assessing the reflectance color spectra of a wide range of sample surfaces. The device offers precise determination of color difference values, formulas, and indices in common color spaces, ensuring reliable performance in both laboratory and field environments. Its intuitive 3.5-inch TFT color LCD touchscreen and large internal memory further enhance usability and data management.
