Product ID:CM-NR20XE

CM-NR20XE with φ20mm extended aperture and stable end face can test surface stripe and wet products.  

Difference between CM-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, CM-NR20XE is a vertical structure. When measuring, it can make sure only the aperture touches the object which will not stain the instrument body. 

Product Introduction

CM-NR20XE is a handheld colorimeter based on 45°/0° optical geometry. Its measuring aperture is 20mm. CM-NR20XE measuring aperture is the biggest one in domestic. Meanwhile, it also has high measuring precision. As a member of Lab-kits 45°/0° colorimeter, CM-NR20XE is a colorimeter with unique performance. The color measurement results from CM-NR20XE simulate human eyes but its accuracy is several times higher than human eyes. CM-NR20XE 45°/0 ° optical geometry structures can reflect interactive effect between surface stripe and sample color more effectively than 8°/d colorimeter. CM-NR20XE will eliminate the errors between human eyes and color tester caused by surface stripe when judging tolerance critical value of sample colors. Therefore, CM-NR20XE is widely used in color field.

QC Department
CM-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.
