Color meer,color difference meter( colour difference meter) is the meter to measure the color difference between samples.

This portable color difference meter can be used to measure the hue of all colors, and measure accurately CIE_Lab color, CIE_XYZ color, CIE_xyY color. Also, it can display directly the color difference between two samples. It is small, stable, precise,reliable, light and easy to operate. It can measure variously smooth surfaces. It is excellent in performance, mainly used in color matching of color system in costumes,plastic, furniture, architecture and upholstery etc, also applicable in design, printing, costumes and dyeing etc. Easily to use, enhances the working efficiency greatly and reduces the communication cost.

1. Compact size and light weight (about 203g without batteries)
2. Easy, one-handed operation
3. Color difference displayed in terms of Delta(L*a*b*) or Delta(L*C*H)
4. Adopt high speed spectral analysis system of CCD
5.Can connect to computer,with software and printer
6. Low price, high quality

Technical Features

  1. Widely applied to quality control of plastic and printing industries’
  2. Display directly color difference by △E*ab、△L*a*b、CIE­­­­_L*a*b、CIE­­­­_L*c*h
  3. Standard deviation within  △E*ab0.2(test condition;choose average values by white board)
  4. It can be connected to computer to do the inspection by software with USB interface

measure any color of smooth surface

    • Main characteristic
    • compare the color difference between sample and the measured subject ,then output CIE_Lab 3 groups data, and the 4 groups of △E、△L、△a、△b data after comparision.
    • the colorimeter is portable ,and two kinds of power supply way are respectively battery and external power supply.It is very convenient.
    • USB expansion connection is provided and is very conveniently connected to PC. That is advantage for preserving data and printing report form.
