Product Overview

High performance-price ratio among international similar products

As China’s spectrophotometer, it integrates multiple innovative technical characteristic,

and extends the boundary of on-site color quality control during production;

  • It can be applied to laboratories, factories and on-site operations, and can achieve the best color
    management across all application fields’quality control;
  • Allows medium and small companies to obtain high performance color management system with relatively low price;
  • The software contains all necessary color equations, standard light sources, and a large number of standards for specific industries and applications;
  • Operation system supports both English and Chinese interfaces, and we offer to design the interface in other languages based on the need of our customers.
  • Professional design, powerful instrument functions
  • Professional horizontal design and it does not have any moving parts, which avoids the shaking of the instrument during measurement process. This makes the measurement more accurate; PC software for easy measurement data management;
  • Different measurement caliber for A and B. Testing ports for the two instruments are to the left. Can measure both SCI and SCE at the same time. Large data storage space: can store up to 100 sets of standard samples, with up to 200 measurement records for each standard sample;
