BIUGED insistson independent research whose technology innovation is unique in color management field. BGD 556 is the most convenient colorimeter for users.

Leading Humanity Design and Convenient Operation

  • Auto White and Black Calibration at Startup
  • Structure design in line with Ergonomics
  • Fool-style Operation Interface

Stable Measurement Performance

  • The average fluctuation of △E is less than 0.06, actually more in 0.03~0.05.
  • Portable structure design which is more conductive to keeping the instrument stable whenusing.

Flexible and Accurate Locating

  • Camera locating can solve the problem of locating a small area. The minimum width of locating is 4mm.
  • Illumination locating is a fast, simple and convenient locating function which is the original function by 3nh.

More Measurement Modes

  • Three measuring apertures for more circumstances.
  • Five color spaces for more color schemes selection.
  • Three light sources for more circumstances.

PC Software – Realize More Function Expansion

  • BIUGED has the intellectual property of PC software. The corresponding software serial number and password protection are configured in BGD colorimeter.
  • Be able to perform color difference analysis, color difference cumulative analysis, chromaticity index, color sample data base management, simulating object color, etc.

Advance Power Management Design

  • BIUGED is the first enterprise using high capacityLi-ion battery in colorimeter.
  • BIUGED Li-ion battery can berepeatedly charged which will save cost. Meanwhile, it can measure more than3000 times on one charge to ensure the stability of long time measurement.
