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.
