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?
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!

- 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
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:
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.
