INTRODUCTION
MEWOI-XF38 Colorimeter is a professional colorimeter designed and produced subject to the relevant standards of International Commission on Illumination (CIE) and national stands. Being with brand new imported key components, the instrument is well designed and features in precision, stability, easy handling, easy to learn and cost-effective. MEWOI-XF38 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. 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... |
MAIN FEATURES
