Product Descriptions
The instrument made in accordance with the development of the international CIE standard for color difference measurement .The equipment is in line with International standards.Its characteristics are stable performance. high precision,easy to carry and are especially suitable for the production, operation   surveying in the  scene. The instrument can rapidly and accurately measure color contrast value from the same material.It uses the LCD display technology to make sure easy  understanding .The instrument can be used to measure color contrast value from the same material
Accurately,i,e,â–³E,â–³L,â–³a,â–³b,Lab and Lch value.The equipment is mainly applied to the  plastic ,,metal ,printing and painting industries .     Â
   The additional power controlling functions ensure the accuracy. It will have the suggestive buzzing when measuring.

Working theory
 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 comparison .
                   CIE color interspace chart
      Â
â–³E stands for the total color difference.
â–³L+ stands for partial white ,â–³L- stands for partial black (comparing with prototype )
â–³a+ stands for partial red ,â–³a- stands for partial green (comparing with prototype )
△b+ stands for  partial yellow,△b-stands for partial blue (comparing with prototype )
Â
| Color dif, scope | Color dif. analysis |
| 0 - 0.25 â–³E | Very small or no; very perfect matching |
| 0 25 - 0.5 â–³E | Small;acceptable matching |
| 0.5 - 1.0â–³E | Small to medium; acceptable in some areas |
| 1.0 - 2.0 â–³E | Medium ;acceptable in some areas |
| 2.0 - 4.0â–³E | Has distance;acceptable in special applications |
| 4.0â–³E | Very big ;not acceptable in most applications |
