3nh Liquid Spectrophotometer NR200 televisions or microwave ovens
for heating food colour contrast analyzer
At my new quality assurance job, one of our product quality checks
is to measure the color of our product and to ensure that we are
producing our product that is within a preset acceptable color
range. We use an instrument, a spectrophotometer, that reports
Hunter L, a, b; XYZ, and L*a*b scales. I’ve always thought that
color was measured in terms of RGB, like the way computer monitors
and TV screens describe color. I’ve even created custom colors for
fonts on my computer by manually adjusting the RGB quantities. Can
someone explain why we would measure color using Hunter L, a, b;
XYZ, and L*a*b instead of RGB?
It depends on what you want. Do you want White, Yellowish White, or
Bluish White?
Product Description
NR200 Liquid Spectrophotometer is another mainstream brand colorimeter introduced by 3nh which has
synthesized the advantages of ten more traditional imported
colorimeters and has experienced ten thousands tests and applied
many innovative technologies. Accurate, Stable, Exquisite and
Affordable!
Main Advantages
a. Leading Humanity Design and Convenient Operation
One-touch access to measurement interface
Structure design in line with ergonomics
East-to-use operating interface
b. Stable Measurement Performance
The repeatability △E is 0.08.
Portable structure design which is more conductive to keeping the
instrument stable when using.
c. Convenient and Fast Locating
Illumination locating is a fast, simple and convenient locating
which created by 3nh.
d. PC Software—Realize More Function Expansion
3nh has the intellectual property of PC software. The corresponding
software serial number and password protection are configured in
3nh colorimeter.
Be able to perform color difference analysis, color difference
cumulative analysis, chromaticity index, color sample database
management, simulating object color, etc.
e. Advanced Power Management Design
3nh is the first enterprise using high capacity Li-ion battery in
colorimeter.
3nh Li-ion battery can be repeatedly charged which will save cost.
Meanwhile, it can measure more than 3000 times on one charge to
ensure the stability of long time measurement.

Color Space
CIE LAB
- L(Lightness)-0 is black,100 is white
- a(Red-Green)-positive values are red; negative values are green
and 0 is neutral
- b(Blue-Yellow)-positive values are yellow;negative values are
blue abd 0 is neutral
CIE LCH
L: Lightness,value is the same in each scale C:Chroma H:Hue Angle
dE Total Color difference
Delta-E is a measurement used to indicate how much a color deviates
from an accepted standards.The higher the dE, the more inaccurate
the color.
Color difference knowledge:
Warranty
All color spectrophotometer and colorimeters have one year warranty
from the purchase date. If it has something wrong during warranty,
you can send it back to us. The buyer pays for the returning
shipping cost and we will pay for the sending shipping cost.
