NR20EX Color Difference Meter Colorimeter
OVERVIEW
NR20XE precision colorimeter with φ20mm extended aperture and stable end face can test surface stripe and wet products.
NR20XE 45°/0 ° optical geometry structures can reflect interactive effect between surface stripe and sample color more effectively than 8°/d colorimeter. 
FEATURES
- The 20mm large measuring aperture can accurately measure items with surface textures
- Vertical structure, can measure the wet surface or put it in liquid for measurement
- The dual positioning function of illumination and cross makes measurement easier
- Adopt 3nh original new super optical path and dynamic integration time, which has higher measurement stability and measurement accuracy
- The measured 45°/0° optical geometric design consistent with the visual inspection, taking into account the influence of the surface characteristics of the article
- Ring light design, suitable for materials with polarized light (polarization)
- Adopt large-capacity rechargeable polymer lithium-ion battery, no need to buy batteries repeatedly
- Configure high-end CQCS3 color quality management software, which can be connected to a computer for use

FQA
Q1: How does a colorimeter work?
A: A colorimeter is a device that mimics the way humans perceive color. How does a colorimeter work? Using an internal light source, a colorimeter shines light down onto the surface of the sample. As the light reflects back up to the device, it passes through three filters: red, green and blue.
Q2: What does colorimeter mean?
A: Definition of colorimeter. : an instrument or device for determining and specifying colors specifically : one used for chemical analysis by comparison of a liquid's color with standard colors.
