Overview
QIWEI WSB-3Y whiteness meter is a Benchtop microcomputer whiteness meter, which can determine whether the sample contains Fluorescent Whitening Agent. The whiteness meter is composed of Illuminant, Optical inspection system, detection system, microcomputer data processing and display system, etc., using high-quality components, microcomputer configuration, stable performance and accurate measurement. Measurement range is 0~ 199.9, and the Opacity of thin sheet materials can be measured using d/0 illumination conditions.
Features
1. Microcomputer configuration, touch keyboard, LCD backlit LCD display
2, color measurement performance is stable and accurate, using CAD, simple operation, can accurately measure paper Opacity
3. The modified color filter system makes the overall Light spectrum characteristics of the whiteness meter fully comply with the CIE standard Observer Response Linear dispersion, which can accurately measure ISO whiteness value
4. Stability and reproducibility are very high, completely eliminate system drift error, and have Data storage query function to meet GLP requirements
5. Using imported high-quality original devices, high efficiency, low circuit power consumption, reasonable introduction of optical path design, Reliability is quite good
6. Automatic calibration, Average Measurement mode, Data storage and query
Principle
The WSB-3Y 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.
Standards
GB2913 "Plastic whiteness test method", GB5950 "Building materials and Non-metallic mineral products whiteness Measuring method", GB8940.1 "Pulp whiteness measurement method", GB13025.2 "Salt industry general test method, measurement of whiteness", GB12097
Notice
• WSB-3Y 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/WSB-3Y 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
