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.

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 body.

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.

NR20XE Colorimeter is under warranty for 12 months from the purchase date. Customers must provide warranty card and valid proof of purchase.

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.
