Overview
The QIWEI WSB-3 whiteness meter is a Benchtop microcomputer whiteness meter, in which the WSB-3Y fluorescent whiteness meter can determine whether the sample contains Fluorescent Whitening Agent. The instrument is composed of Illuminant, Optical inspection system, detection system, microcomputer data and display system, etc. It adopts high-quality components and microcomputer configuration, with stable performance and accurate measurement. Measurement range is 0~ 199.9, and d/0 illumination conditions can be used to measure the Opacity of thin sheet materials.
Features
1. Microcomputer configuration, touch keyboard, LCD backlit LCD display
2. The color measurement performance is stable and accurate, and the CAD operation is simple, which can accurately measure paper Opacity
3. The modified color filter system makes the overall Light spectrum characteristics fully comply with the CIE standard Observer Response Linear dispersion, which can accurately measure ISO whiteness value
4. Stability and high reproducibility, completely eliminate system drift error, with Data storage query function, to meet the needs of GLP
5. Using imported high-quality original devices, high efficiency, low circuit power consumption, reasonable introduction of optical path design, Reliability
6. Automatic calibration, Average Measurement mode, Data storage and query
Principle
The WSB-3 whiteness meter uses the principle of photoelectric conversion and the analog-to-digital conversion circuit to measure the radiant luminance energy value of the white reflection on the surface of the sample. After signal amplification, A/D conversion and data processing, the corresponding whiteness value is finally displayed.
Applications
Paper, Plastics, Building Materials, Non-metallic Minerals, Salt Industry
Standards
GB2913、GB5950、GB8940.1、GB13025.2、GB12097
Notice
• WSB-3 whiteness meter is a Measurement instrument, do not disassemble at will
Should be used in a working environment without corrosion gases or vibration sources
• During use, there should be no strong Illuminant irradiation and strong magnetic field interference around, the air should be drying, and there should be no dust and other floating objects
• The tested sample must not fall into the measurement cylinder of WSB-3 whiteness meter, so as not to be able to zero
• Optical inspection components cannot be directly touched by hand
• The black cylinder and working whiteboard should be kept clean and not contaminated to avoid affecting Precision
