The Automatic Colorimeter is a high-precision color measurement instrument built on the latest 32-bit ARM processor and advanced optoelectronic technology. Featuring a 5-inch TFT color touchscreen and driven by an imported micro-motor, it truly realizes one-touch automatic testing. It efficiently measures reflected color, color difference, and over ten key parameters including ISO brightness (R457 blue-light whiteness), fluorescent whiteness, CIE Ganz whiteness (W10 and tint value TW10), ceramic whiteness, building material whiteness, Hunter Lab and whiteness, yellowness, opacity, transparency, light scattering coefficient, light absorption coefficient, ink absorption value, and custom whiteness. The instrument adopts a mechatronic integrated structure with a halogen lamp source, a 150mm integrating sphere, and a UV cut-off filter, strictly simulating the D65 standard illuminant and complying with d/o geometric conditions. Equipped with a high-speed silent thermal printer, it is a standard precision instrument for color management, quality control, and new product R&D in papermaking, textile, ceramic, building materials, chemical, food, and salt industries.
