WF28 Digital Colorimeter Color Difference Tester with Two Kinds of Color Modes Measuring Aperture 8mm

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.
