Introduction of XW18 Portable Colorimeter:

Hand-held colorimeter XW18 is years of painstaking development of the high-precision colorimeter, serially developed according to the measuring requirements on different products and gain many optimal achievements with cost performance.

It can be applicable in textile, printing and dyeing, clothing, footwear, leather, chemicals, plastics, film, pigments, paints, inks, metal, photography, toys, food medicine and other liquid, powder and special industry for color quality control, color analysis, sample testing, production line testing, also suitable for injection molding, ink, paint, spray and other color industries. Also extensive used in researching institution and laboratory. It can precisely measure kinds of color index in color space, help to analyze color matching freely and color management, with color analysis software, it will extend more functions.

Aperture 4mm is specially design, considering small area and curvature measurements. It is suitable for measuring small device, gadget, small parts etc.

Aperture 8mm version is a general-purpose color difference meter, mostly used on flat surface materials. It provides great convenience and trustworthy reliability for its versatility, tiny table difference, and stability.

Aperture 40mm can be used for huge textured, uneven and pitting surface, also wet sample, like meat, fish...
