A colorimeter is a color measuring instrument widely used in various fields, which can be used to detect the color and whiteness values of the surface of products. In this article, we will take a closer look at how the colorimeter NR4520 detects the whiteness value of a product.

1. Introduction to the colorimeter NR4520.

Colorimeter NR4520 is a high-precision color measuring instrument with high resolution, high precision, high stability and other characteristics. It uses advanced measurement technology to quickly and accurately measure the color and whiteness values of the product surface.

2. The detection principle of the colorimeter NR4520.

The colorimeter NR4520 uses the CIELAB color space as a measurement standard to calculate color and whiteness values by measuring the reflected and transmitted light on the surface of the product. Specifically, it uses an integrating sphere measurement method in which a product is placed inside an integrating sphere and the color and whiteness values are calculated by measuring the reflected light from the surface of the product. At the same time, it also uses a transmission measurement method to calculate color and whiteness values by measuring the transmitted light on the surface of the product.

3. Measurement steps of colorimeter NR4520.

1.Place the product inside the integrating sphere, making sure that the surface of the product is parallel to the inner wall of the integrating sphere.

2.At the press of the measurement button, the colorimeter NR4520 begins to measure the reflected and transmitted light on the surface of the product.

3.Once the measurement is complete, the colorimeter NR4520 automatically calculates the color and whiteness values and displays the results on the screen.

4. Precautions for colorimeter NR4520.

1.Before measuring, it should be ensured that the surface of the product is clean, free of impurities, no scratches, etc.

2.When measuring, avoid direct light on the surface of the product, so as not to affect the measurement results.

3.During use, care should be taken to keep the colorimeter NR4520 clean and dry, so as not to affect the measurement results and service life.

In conclusion, the colorimeter NR4520 is a high-precision color measuring instrument that can be used to detect the color and whiteness values of the product surface. During use, care should be taken to keep the instrument clean and dry to ensure the accuracy and stability of the measurement results.
