Food texture color analyzer machine large aperture color comparator colorimeter

          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 body. 

            QC Department

 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.

            Applications

 Food, medicine, textile, non-woven fabrics, denim, dyeing and printing, color steel plate, paper, plastic, chemical, coating, ink, building material industries, etc.

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.

 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.
