Introduction: 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 (△ E * 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.
