HP-2132 Portable color difference meter

Product Information
Brand: inteke

class：Portable color difference meter

spec：HP-2132

use：Widely applied to quality control of plastic and printing industries’

◆ Profile

In 1931, the CIE(Commission Internationale De L'E'clalrage)setup a series of visible spectrum color space standards．The Basic CIE color space standardS iS CIE_XYZ．lt iS built on standard visual observerson the basis of ability to see, and it reflects the standardS scope of color by eye．Based On CIE_XYZ there are CIE_XvY, CIE_Lab, CIE Lch standard color space, etc.

At present, the CIE Lab color space iS the most commonly used in the industry．In ClE Lab color space, L value stands for color brightness and a value stands for the Green-0n-red value．and b value stands for the blue—on—yellow color value．If determine a value of color by only a group Lab, it will be not practical．However,we can determine the differences among them by comparing two groups of Lab values．

◆ Technical Features：

> Easy operation make you use it easily

> Widely applied to quality control of plastic and printing industries’

> Display directly color difference by △E*ab、△L*a*b、CIE_L*a*b、CIE_L*C*h

> Standard deviation within△E*ab0.2(test condition：choose average values by 12pcs white tabula)

> It can be connected with computer to do the inspection by software with USB expansion interface．

◆ Workin~theory
Compa re 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
△E stands for the totaI color difference.
△L+stands for partial white, △L-stands for partial black(cornpa ring with p rototype)
△a+stands for pa rtial red, △a—stands for partial green(comparing with p rototype)
△b+stands for pa rtial yellow, △b-stands for pa rtial blue(comparing with plrototype)
