Overview
WSB-1Y portable fluorescence whiteness meter whiteness meter
Product Details
The digital fluorescence whiteness meter is composed of a light source, optical system, detection system, data processing and display system, etc.
Fluorescence whiteness meterBy utilizing the principle of photoelectric conversion and using an analog-to-digital conversion circuit, the radiance energy value of the white reflection on the surface of the measured sample is amplified, A/D converted, and processed to display the corresponding whiteness value. 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.
WSB-1Y portable fluorescence whiteness meter
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-1Y portable fluorescence whiteness meter features:
1. Adopting a large screen high-definition LCD display, it has comfortable reading and is not affected by natural light.
2. Adopting low drift high-precision integrated circuits and high-efficiency long-life light sources can effectively ensure the long-term stable operation of the instrument.
3. Reasonable and concise optical path design can effectively ensure the correctness and repeatability of measurement values.
4. Simple operation can accurately measure the opacity of paper.
5. Using a national calibration whiteboard to transmit standard values ensures accurate and reliable measurement.
