The overall whiteness of the material in the WSB-3Y desktop fluorescence whiteness meter (whiteness meter) is R457

Overview of WSB-3Y desktop fluorescence whiteness meter (whiteness meter):

The microcomputer based fluorescence whiteness meter consists of a light source, optical system, detection system, microcomputer data processing and display system, etc. The overall whiteness of the substance is R457. R457=blue light whiteness r457+fluorescent whitening F

The whiteness of an ideal surface with a spectral diffuse reflectance ratio of 1 is defined as 100, and the absolute whiteness of a black surface with a spectral diffuse reflectance ratio of 0 is defined as 0.

The WSB-3Y desktop fluorescence whiteness meter (whiteness meter) is designed completely according to the standard light source and lighting conditions specified by the International Commission on Illumination (CIE). Through strict testing and debugging, and in accordance with the enterprise standard Q/TDKY02-2004, it can be applied to national standards such as GB2913, GB5950, GB8940.1, GB12097, GB13025.2, etc.

Intelligent desktop whiteness meter (whiteness meter)

Working principle of WSB-3Y desktop fluorescence whiteness meter (whiteness meter):

The instrument utilizes the principle of photoelectric conversion and adopts an analog-to-digital conversion circuit to measure the radiance energy value of the white reflection on the surface of the sample. After signal amplification, A/D conversion, data processing, and finally display the corresponding whiteness value.

WSB-3Y desktop fluorescence whiteness meter (whiteness meter) Usage:

The WSB-3Y desktop fluorescence whiteness meter (whiteness meter) can be widely used for measuring the whiteness of objects such as textile printing and dyeing, paint and coatings, chemical building materials, paper and cardboard, plastic products, white cement, ceramics, enamel, porcelain clay, talcum powder, starch, flour, salt, detergents, cosmetics, etc. The opacity of paper can be calculated through measurement.

1. Measure the diffuse reflectance factor (r457) of the sample at 457nm for blue light, referred to as "blue light whiteness r457"

2. The determination of whether the sample contains fluorescent whitening agents and the measurement of the fluorescence whiteness value generated by fluorescence emission is called "fluorescence whitening F" or "whitening F".

WSB-3Y desktop fluorescence whiteness meter (whiteness meter) features:

1. Measure the r457 value and fluorescence whitening F value of the test substance at once. This method is easy to use and the measurement values are accurate.

2. The operation interface is simple, and according to the workflow in the appendix, you can directly master the operation method.

3. Adopting a large screen high-definition LCD display, it has comfortable reading and is not affected by natural light.

4. By using low drift high-precision integrated circuits and high-efficiency long-life light sources, the instrument can effectively ensure long-term stable operation.

5. Reasonable and concise optical path design can effectively ensure the correctness and repeatability of measurement values.

6. Simple operation can accurately measure the opacity of paper.

7. Using a national calibration whiteboard to transmit standard values ensures accurate and reliable measurement.

Precautions for using WSB-3Y desktop fluorescence whiteness meter (whiteness meter):

This instrument is a measuring device and must not be disassembled at will. Please read the instructions carefully before use.

1. The working environment should be free of corrosive gases and vibration sources.

2. There should be no strong light sources or strong magnetic field interference around.

3. The surrounding air should be dry and free of floating objects such as dust.

4. After the instrument is stopped for a long time, the preheating time should be correspondingly extended to improve stability.

5. The power supply voltage must meet the working conditions.

6. Do not drop the sample into the measuring cylinder to avoid being unable to zero.

7. Do not touch optical components directly with your hands to avoid affecting their spectral characteristics.

8. Do not contaminate the black tube and work whiteboard to avoid affecting accuracy.
