Precise Colorimeter WF28 8mm Color meter Measurement Caliber 8mm



Precision colorimeter  is a professional R & D and production of national standards based on the relevant standards of the International Commission on Illumination CIE colorimeter. The chromatic meter adopts the brand-new imported key components, through elaborate design, stable precision, simple operation and easy to understand, economical and practical characteristics. 


WF28 colorimeter with competitive price, has these advantages of being easy to operate, easy to understand, affordable and so on. WF28 only have one measuring light source (D65); two kinds of color modes (CIE1976LAB, CIELCH); one color difference formula ( ΔE * ab); two language pattern (Simplified Chinese and English), and a universal measuring caliber (8MM) . WF28 colorimeter can store 100 standard data and 20000 sample data, you can also add mini-printers to do real-time printing measurement data. It can’t operate with "color analysis system" software functions.
