Product Summary:

HZ-5502 Portable color difference meter. 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.

Application

Measure any color Of smooth surface

△E*ab=[(△L*)2+(△a*)2。+(△b*)2]1/2

△L*=Lsample一L*standard(lightness difference)

△a*=a*Lsample一a* standard(red/green diference)

△b*=b*Lsample—b standard。mmd(yellow/blue difference)

Working 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)

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.
