Qiwei WSB-3Y Whiteness Meter is a desktop microcomputer Whiteness Meter, which can determine whether the sample contains fluorescent brightener.The Whiteness Meter is composed of a light source, an optical system, a detection system, a microcomputer data processing and display system, etc. Using high-quality components, microcomputer configuration, stable performance and accurate measurement.The measurement range of WSB-3/WSB-3Y Whiteness Meter is 0~199.9, and the opacity of thin sheet materials can be determined by using the illumination condition of d/0.
Qiwei WSB-3Y Whiteness Meter is a standard Whiteness Meter, designed and developed in strict accordance with the standard light source and illumination conditions stipulated by the International Commission on Illumination CIE, in line with GB2913 "Plastic Whiteness Test Method", GB5950 "Building Materials and Non-metallic Mineral Products Whiteness Measurement Method", GB8940.1 "Pulp Whiteness Determination Method", GB13025.2 "Salt Industry General Test Method, Whiteness Determination",GB12097and other national standards.
1、The WSB-3Y Whiteness Meter is a microcomputer configuration, touch keyboard, LCD backlit LCD display.
2. The color measurement performance is stable and accurate. CAD is easy to use and can accurately measure the opacity of the paper.
3、The modified color filter system used in the WSB-3Y Whiteness Meter makes the overall spectral characteristics of the Whiteness Meter fully conform to the CIE standard observer response curve, and can accurately measure the ISO whiteness value.
4. The stability and reproducibility are very high, the system drift error is completely eliminated, and the data storage query function is used to meet the needs of GLP.
5. The Whiteness Meter adopts imported high-quality original components, with high efficiency, low circuit power consumption, reasonable and brief optical path design, and good reliability.
6. It has the functions of automatic calibration, average measurement mode, data storage and query.




WSB-3Y Whiteness MeterUsing the principle of photoelectric conversion, the analog-to-digital conversion circuit is used to measure the radiant brightness energy value of the white reflection on the surface of the sample, and finally display the corresponding whiteness value through signal amplification, A/D conversion, and data processing.
1)The WSB-3Y Whiteness Meter is a measuring instrument and should not be disassembled at will.
2) It should be used in a Operating Environment without corrosive gases or vibration sources.
3) During the use process, there should be no strong light source irradiation and strong magnetic field interference around, the air should be dry, and there should be no dust and other floating objects.
4) The tested sample must not be droppedWSB-3/WSB-3Y Whiteness Meter in the measuring cylinder, so as not to be able to zero it.
5) Optical components cannot be directly touched by hand.
6) The black cylinder and the working whiteboard should be kept clean and not contaminated to avoid affecting the accuracy.
