|Brief Introduction :|
NR20XE with φ20mm extended aperture and stable end face can test
surface stripe and wet products.
3nh NR20XE is a handheld colorimeter based on 45°/0° optical
geometry. Its measuring aperture is 20mm. NR20XE measuring aperture
is the biggest one in domestic. Meanwhile, it also has high
measuring precision. As a member of 3nh 45°/0° colorimeter, NR20XE
is a colorimeter with unique performance. The color measurement
results from NR20XE simulate human eyes but its accuracy is several
times higher than human eyes. NR20XE 45°/0 ° optical geometry
structures can reflect interactive effect between surface stripe
and sample color more effectively than 8°/d colorimeter. NR20XE
will eliminate the errors between human eyes and color tester
caused by surface stripe when judging tolerance critical value of
sample colors. Therefore,NR20XE is widely used in color field.
|Difference between NR20XE and Ordinary Portable Colorimeter|
When testing products such as meat by ordinary colorimeter, the
whole instrument body has to be placed in the object which not only
stains the instrument, but also will let the liquid/water enter the
instrument directly and bring cross contamination. However, NR20XE
is a vertical structure. When measuring, it can make sure only the
aperture touches the object which will not stain the instrument
NR20XE can meet quality control requirements in plastic
(PET,PE,PP,PTA,ABS,EVA particles and powder), color steel plate,
coating, textile, fluorescent material, denim, medicine and food
industries, etc. It can help to control product color difference,
improve product competitiveness, reduce enterprises’ loss and
control production cost.
Food, medicine, textile, non-woven fabrics, denim, dyeing and
printing, color steel plate, paper, plastic, chemical, coating,
ink, building material industries, etc.

|Why us ?|
|3nh analyzed the parameters from Japan,American and Germany spectrophotometers. The differences of L*ab
absolute value between them are within ±1.5. Compared the L*ab value between NS800 and Japan spectrophotometer,
when measuring any color objects, the biggest L*ab difference is
within ±1.0. This is a breakthrough of 3nh high technology|
which realizes to be fully compatible with international market.
|Our service :|
NR20XE Colorimeter is under warranty for 12 months from the purchase date. Customers
must provide warranty card and valid proof of purchase.

-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.
