JinKeLian WSB-2Y digital display Whiteness Meter is a desktop digital display fluorescent Whiteness Meter with a measurement range of 0~199. WSB-2Y digital display Whiteness Meter is composed of light source, optical system, detection system, data processing and display system, etc. The overall whiteness is R457. R457=blue light whiteness r457+fluorescence whitening degree F. WSB-2Y digital display Whiteness Meter is designed in strict accordance with the standard light source and lighting conditions stipulated by the International Commission on Illumination (CIE).
Define the whiteness of a desirable surface with a spectral diffuse reflectance of 1 as 100, and an absolute black surface with a spectral diffuse reflectance of zero as 0.
1. Large-screen high-definition LCD liquid crystal display, with clear and comfortable readings, not affected by natural light.
2. Low-drift and high-precision integrated circuit, the light source has an effective and long life, which can effectively ensure the WSB-2Y digital display Whiteness Meter to work stably for a long time.
3. The national calibration whiteboard is used to transmit the standard value, and the measurement is accurate and reliable.
4. The optical path design is reasonable and simple to ensure the correctness and repeatability of the measured values.
5. It is easy to operate and can accurately measure the opacity of paper.
It is suitable for whiteness measurement ofchemical building materials, paper cardboard, plastic products, white cement, paint coatings, ceramics, textile printing and dyeing, enamel, porcelain clay, flour,salt, talcum powder,The opacity of paper can be calculated by measuring it.
1) Measure the blue light 457nm diffuse reflection factor (r457) of the sample, which is called "blue light whiteness r457".
2) Determine whether the sample contains fluorescent whitening agent, and measure the fluorescent whiteness value generated by fluorescent emission, which is called "fluorescent whitening degree F" or "whitening degree F".

Implement enterprise standard Q/TDKY02-2004, applicable to GB2913, GB5950, GB8940.1, GB12097, GB13025.2 and other national standards.
The WSB-2Y digital display Whiteness Meter uses the principle of photoelectric conversion and an analog-to-digital conversion circuit to measure the radiant brightness energy value of the white reflection on the surface of the sample. After signal amplification, A/D conversion, and data processing, it finally displays the corresponding whiteness. value.
